Question

Charge on the second sphere q2 = 3 x 10-7C, q1 = 2 x 10-7C Distance between the spheres r = 30cm = 0.3m then electro static force between the sphere

Answer 1

Charge on the second sphere q2 = 3 x 10-7C, q1 = 2 x 10-7C Distance between the spheres r = 30cm = 0.3m then electro static force between the sphere

Answer:

Charge on the first sphere,  C Charge on the second sphere,  C Distance between the spheres, Where,  Permittivity of free space Hence, force between the two small charged spheres is  N. The charges are of same nature. Hence, force between them will be repulsive.
