QUESTION #42 Electric Potential and Field
Electric field in a region is given by E = Ax i + By j, where A = 10~V / m² and B = 5~V / m². If the electric potential at a point (10, 20) is 500~V, then the electric potential at origin is \_\_\_\_ V.

QUESTION #43 Charged Pendulum in Electric Field
A simple pendulum has a bob with mass m and charge q. The pendulum string has negligible mass. When a uniform and horizontal electric field E is applied, the tension in the string changes. The final tension in the string, when pendulum attains an equilibrium position is \_\_\_\_. (g : acceleration due to gravity)
