Question

A 500 microcoulomb charge is at the centre of a square of side 10cm .Find the work done in moving a charge of 10mc between two diogannly

Answer 1

Explanation:

Electric potential by charge 500 μC at the diagonally opposite points on the square is same.  

So the potential difference is zero between the diagonally opposite points on the square. 

Work done = Potential difference x charge = zero

Answer 2

Answer:

Potential Difference × Charge = ( 0 ) Zero
