Question: If the length of the pendulum is made 9 times and mass of the bob is made 4 times, then the value of time period becomes:
A) 3T
B) 3T2
C) 4T
D) 2T
The time period of a pendulum is given by the formula T = 2π√(L / g), where L is the length of the pendulum and g is the acceleration due to gravity. If the length of the pendulum is made 9 times and the mass of the bob is made 4 times, then the time period becomes T = 2π√((9L) / (4g)) = 3T. Therefore, the correct option is A.
