A) 4P
B) P/4
C) 2P
D) P
Correct Answer: C
Solution :
The time period of the iron ball would be given by, \[P=2\pi \sqrt{\frac{M}{K}}\] So, if mass of the ball is increased to 4 times of its initial mass, then the new period becomes \[P=2\pi \sqrt{\frac{4M}{K}}=2P\]You need to login to perform this action.
