A pendulum clock on the surface of the earth has a period of 1.00 s. On a distant planet, the length of the pendulum must be shortened slightly to have a period of 1.00 s. What is true about the acceleration of gravity on the distant planet?
A)The gravitational acceleration of the planet is 0.
B)The gravitational acceleration of the planet is slightly greater than g.
C)The gravitational acceleration of the planet is slightly less than g.
D)There is no gravitational acceleration on the planet.
E)The gravitational acceleration of the planet is equal to g.

The period of a pendulum is given by:$$T = 2\pi \sqrt{\frac{L}{g}}$$where:* T is the period* L is the length of the pendulum* g is the acceleration due to gravityIf the period is to remain the same, then the length of the pendulum must be shortened if the acceleration due to gravity is less.
