Question

Please help solve. The correct answer is "C"

A charged styrofoam ball floats motionless above a uniformly charged sphere. It is held in place by a combination of gravitational and electric forces. The styrofoam ball has a charge of +2.6 nC and a mass of 4.0 g. The uniformly charged sphere has a charge of 35 muC and a radius of 2.0 cm. What is the distance between the styrofoam ball and the surface of the sphere? (Treat the styrofoam ball as a point charge). A 10.79 cm B 14.45cm C 12.45 cm D 1.67 cm E 16.45 cm

Explanation / Answer

distance is asked from surface of 2 c.m sphere you calculated 14.45 cm which is distance from center of sphere

so subtract 2 from your ans = 14.45-2 = 12.45 c.m.
