What is the force of repulsion , if each sphere is charged double the above amount and the distance between them is halved?

Text Solution

Verified by Experts

Now , `q_1 ,q_2 ` both are doubled and r is halved
`F = (1)/(4 pi in _0) (q_1q_2)/(r^(2)) `
F becomes 16 times i.e. F . = 16 .F
F. ` 16 xx 1.521 xx 10 ^(-2) N " or " F. = 0.24 N`
