Four equal charges $Q$ each are placed at four corners of a square of side a each. Work done in carrying a charge $- q$ from its centre to infinity is

Options:

Answer:

Solution:

At the centre $O$ of the square due to four equal charges $q$ at the corners, potential
$V = \frac{4 q}{4 π ε _{0} ( a 2 ) /2} = \frac{2 q}{π ε _{0} a} ∴ W_{0\infty} = - W_{\infty00} = - (- q) V = \frac{2 q ^{2}}{π ε _{0} a}$
