Question

What would be the time period of a simple pendulum at the centre of the earth?

Answer 1

Time period of a simple pendulum is T = 2π sqrt (1/g). When g = 0, sqrt (1/g) = infinity. Hence T = Infinity @ center of earth for simple pendulum. [ - ] The gravitational force inside the earth is directly propositional to the distance from the center of earth such that.
