Glass ball is rubbed with ebonite ball and kept at a separation of 1 cm. If the force of attraction between them is 10 N, find charge on each ball.

Text Solution

Verified by Experts

Given , F = 10 N,
` " " d= 1 cm = 10 ^(-2) m`
` therefore " " F = (kq_1q_2)/(d^(2)) =(kq^(2))/(d^(2))`
` rArr " "q^(2) = (10 xx (10^(-2))^(2))/(9xx 10 ^(9))`
` rArr " " q= (1)/(3) muC `
