**The bob of a simple pendulum has mass 2g and a charge of 5.0 μC. It is at rest in a uniform horizontal electric field of intensity 2000 V/m. At equilibrium, the angle that the pendulum makes with the vertical is – (take g = 10 m/s ^{2})**

**(1) tan ^{–1} (5.0)**

**(2) tan ^{–1} (0.5)**

**(3) tan ^{–1} (0.2)**

** (4) tan ^{–1} (2.0)**
