If the length of a simple pendulum is halved then its period of oscillation is (a)doubled (b)halved (c)increased by a factor (d) decreased by a factor
option D. The term of a pendulum is immediately proportional to the rectangular root of its period. So, if the duration increases, its term additionally increase. It way that it takes longer to finish one oscillation. So while its duration is halved, its term is reduced via way of means of a aspect of 2.
