Two charges A and B of magnitudes +8.0 pC each, are kept at points (2,1) and (2,7) respectively in a Cartesian coordinate system measured in meters. If the charges are in a vacuum, calculate the force of A on B.
• A. 0.8 × 10-2 N, + y direction
• B. 0.8 × 10-2 N,- x direction
O C. 1.6 × 10-2 N, + x direction
• D. 1.6 × 10-2 N,- y direction
• E. 1.6 × 10-2 N, + y direction
