Two large, flat, parallel, conducting plates are o.04 m apart. the upper plate is at a potential of 10 v with respect to ground. what is the potential at p.

Two large, flat, parallel, conducting plates are O.04 m apart, as shown above. The lower plate is at a potential of 2 V with respect to ground. The upper plate is at a potential of l0 V with respect to ground. Point P is located 0.01m above the lower plate. The electric potential at point P is (A)10V B) 8V C) 6V (D) 4 V
