Question

A 500 micro farad charge is at the centre of square of side 10cm find the work done in the moving of charge of 10 micro farad between the two diagonal opposite of the same square

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:

Potantial Difference × Charge = Zero
