Two identical charges are placed at a separation of 1.0 m. What should be the magnitude of each charge, so that each one repels the other with a force of 36 kg-wt? (Take, g -10 `ms ^(-2 )`)

Given ` q_1 = q_1 =q `
Force of repulsion ` F = (kq_1q_2)/(r^(2))`
` rArr " " q^(2) = ( Fr^(2))/(k) = (360 xx (1)^(2))/(9 xx 10 ^(9))`
` rArr " " q = 200 muC `
