The metallic bob of a simple pendulum of mass 0.5kg carries a positive charge of 0.25 C. If the pendulum is suspended in an electric field of strength 15 NC^{-1} directed from east to west, state the forces actingon the bob and derive the condition for equilibrium. Also find the angle subtended at the equilibrium.(Take g = 10 ms^{-2}) |
