Q. Two objects are charged and their centers are separated by 31.6 cm. Object A is charged to 61 nC and object B is charged to 54 nC. What is the magnitude of the electrostatic force between them?
Q.A small spherical object carries a charge of 3.00 nC. (Note: Assume a reference level of potential V = 0 at r = infinity.) At what distance from the center of the object is the potential equal to the following?
