A positive charge q is placed in front of conducting solid cube at a distance d from its centre. Find the electric field at the centre of the cube due to the charges appearing on its surface.

Options

A. `(1)/(4 pi in_(0)) .(q)/(d^(2))`
B. `(1)/(4 pi in_(0)) .(2q)/(d^(2))`
C. `(1)/(4 pi in_(0)) .(3q)/(d^(2))`
D. `(1)/(4 pi in_(0)) .(4q)/(d^(2))`
