Concept:The time period of a simple pendulum depends on the acceleration due to gravity g.Explanation:The time period of a simple pendulum is T=2πgl.This shows that a higher value of g gives a smaller time period T.The value of g is greater at the poles than at the equator.Therefore, at the poles, the pendulum has a smaller time period and swings faster.Now check the other statements.Simple harmonic motion occurs only for small angular displacements, not large ones. So option A is false.At the equilibrium position, the pendulum has maximum speed, not minimum speed. So option B is false.At the extreme positions, the pendulum has minimum kinetic energy, not maximum kinetic energy. So option C is false.Hence, only option D is correct.Answer:D. It swings faster at the poles than at the equator
