Concept

Problem: A simple pendulum has a period T on Earth. If it were used on Planet X, where the acceleration due to gravity is 3 times what it is on Earth, what would its period be? A) 7 B) 3T C) T/3 D) T/√3E) √3T

FREE Expert Solution

The time period of a simple pendulum is expressed as:

T=2πlg, where l is the length of the pendulum and g is the acceleration due to gravity. 

Now, the new g is given by:

gnew = 3g
