Problem 2. The distance between two charged
It is :
insulated spheres A and B of copper, from centre to
centre is 50 cm:
(a) If charge on each sphere is 6-5 x 10-7 C, then
find out force of repulsion between them.
en electron and proton (b) What will be the force of repulsion if :
(i) charge on each sphere is doubled and distance is
halved. (ii) spheres are placed in water. Given, er
