A pendulum clock is lifted to a height where the gravitational acceleration has a certain value of g. Another pendulum clock of same length, but of double the mass of the bob is lifted to another height where the gravitational acceleration is $$\frac{g}{2}$$. The time period of the second pendulum would be (in terms of period T of the first pendulum)

A. $$\sqrt 2 T$$

B. $$\frac{1}{{\sqrt 2 }}T$$

C. $$2\sqrt 2 T$$

D. T
