One of those detainees was killed, and two others were critically injured. “They called me, ‘Your husband is in the hospital and he’s alive. That’s all we know. Go to the hospital,'” she said. DALLAS – A second bigwins casino victim in the Dallas ICE facility attack has succumbed to his injuries, dying six days after he was shot.
Katy Perry (real name Katheryn Hudson) was born and raised in Southern California. Obviously, two spheres connected by a thin wire do not constitute a typical conductor with a variable radius of curvature. Nevertheless, this result does at least provide a qualitative idea of how charge density varies over the surface of a conductor.
The singer’s North American tour stops are nestled among her previously announced international tour dates. Touring in support of her new album, 143, the global pop superstar will be performing all of her hits, drawing from her extensive catalog. Katy Hudson was raised in southern California, the middle child of two itinerant born-again Christian ministers.
Since Katy Perry’s Capitol Records debut in 2008 with One of the Boys, she has racked up a cumulative 115 billion streams alongside worldwide sales of over 70 million adjusted albums and 143 million tracks. Katy now has six singles and one album for a total of SEVEN Diamond-certified titles. After recording the stripped-down live album MTV Unplugged (2009), Perry returned to the studio. Katheryn Elizabeth Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer, songwriter, and television personality. She is one of the best-selling music artists in history, having sold over 151 million records worldwide. Perry is known for her influence on pop music and her camp style, being dubbed the “Queen of Camp” by Vogue and Rolling Stone.
Gravity is perpendicular to the equipotential surfaces of the gravity potential.In gravity, a hollow sphere has a three-dimensional equipotential region inside, with no gravity from the sphere (see shell theorem). As expected, in the region \(r \geq R\), the electric field due to a charge \(q\) placed on an isolated conducting sphere of radius \(R\) is identical to the electric field of a point charge \(q\) located at the center of the sphere. This means that equipotential surfaces around a point charge are spheres of constant radius, as shown earlier, with well-defined locations. When an object moves against an electric field, it gains energy that is referred to as electric potential energy.
The equation indicates that where the radius of curvature is large (points B and D in Figure 7.40), latex\sigma/latex and E are small. (c) Since the electric field is constant, find the ratio of 100 V to the total potential difference; then calculate this fraction of the distance. Expert educators at Vedantu always stress drawing correct diagrams, paying attention to perpendicularity between field lines and equipotentials, and being alert to traps—such as thinking two equipotential surfaces may cross (they never do). The surface, the locus of all points at the same potential, is known as the equipotential surface. No work is required to move a charge from one point to another on the equipotential surface. In other words, any surface with the same electric potential at every point is termed as an equipotential surface.

Aside from being one of the best-selling musical artists of all time, Katy is an active advocate of many philanthropic causes. In 2013, Katy was appointed a UNICEF Goodwill Ambassador and has used her powerful voice to ensure every child’s right to health, education, equality, and protection. Perry’s initial efforts at mainstream stardom were fruitless, with two separate record labels signing and subsequently dropping her before any material was released. In 2007, however, Capitol Records put out Perry’s EP Ur So Gay, which attracted modest attention for its cheerfully flippant title track. She made a greater splash several months later with the single “I Kissed a Girl,” an assertive ode to sexual curiosity backed by a hard-edged electro-pop beat.
Figure 7.31 shows the electric field and equipotential lines for two equal and opposite charges. Given the electric field lines, the equipotential lines can be drawn simply by making them perpendicular to the electric field lines. Conversely, given the equipotential lines, as in Figure 7.32(a), the electric field lines can be drawn by making them perpendicular to the equipotentials, as in Figure 7.32(b).
The equipotential surface through a point is normal to the electric field at that location for any charge arrangement. Because a conductor is an equipotential, it can replace any equipotential surface. (a) These equipotential lines might be measured with a voltmeter in a laboratory experiment.
