Two charged particles having charge 2.0x...

Two charged particles having charge `2.0xx 10^(-8)C` each are joined by an insulating string of length 1 m and the system is kept on a smooth horizontal table. Find the tension in the string.

Text Solution

Verified by Experts

`Force between the charge particle =tension of string `
` T=(9xx10^9xx(2.0xx10^-8)^-2)/1^2 `
` =3.6xx10^-5N`
