Consider a system where a point charge 'q' is kept at the origin. Another point charge 'Q' is moved from point C (at distance d from the origin along the positive x-axis) to point D (at distance d from the origin along the negative x-axis) along a semi-circular path CRD of radius d. The work done to move the charge 'Q' from point C to point D is:
