# Q 1.12(a):  Two insulated charged copper spheres A and B have their centres separated by a distance of 50 cm. What is the mutual force of electrostatic repulsion if the charge on each is ? The radii of A and B are negligible compared to the distance of separation.

Answers (1)

Since, the radii of the spheres A and B are negligible compared to the distance of separation, we consider them as point object.

Given,

Charge on each of the spheres =

and Distance between them, r = 50 cm = 0.5 m

We know,

Therefore, the mutual force of electrostatic repulsion(Since they have same sign of charge)
