Answer #1

If these spheres are released at precisely the same time, how fast, in meters per second, will they be moving when they are infinitely far away form each other?

Solution.

The type of mechanical energy that solely depends on the state of motion of the body is kinetic energy of that body. This energy cannot be developed for a body that is at rest.

Three identical small metal spheres form an equilateral triangle of side length d = 3.5 cm. Initially, q1 = +2.0 nC, q2 = +6.0 nC, and q3 = ?8.0 nC. Sphere 2 is first moved to touch sphere 1, then moved again to touch sphere 3, and finally returned to the original position. What now is the magnitude of the electrostatic force exerted on sphere 1 by the other two spheres (in N)? The answer was: 1.0*10^4 N
