BOARD 2014: Two equal balls having equal positive charge ‘q’ coulombs are suspended by two insulating strings of equal length. What would be the effect on the force when a plastic sheet is inserted between the two?
Here I think the force would decrease, but in several sources it is given that the force will become zero. So what's correct?

the force will become 0 because there is no attraction or repulshion between same charges.
