If a $10 \mu \mathrm{C}$ charge exists at the centre of a square, the work done in moving a $2 \mu \mathrm{C}$ point charge from corner $A$ to corner $B$ of a square ABCD is

Solution
Due to the $10 \mu \mathrm{C}$ change, potential at all the four corners will be the same
$\therefore \quad$ work done in moving $2 \mu \mathrm{C}$ change from point A to B will be zero.
