A body of mass m is attached to the lower end of a spring whose upper end is fixed. The spring has negligible mass. When the mass m is slightly pulled down and released, it oscillates with a time period of 3 s. When the mass m is increased by 1 kg, the time period of oscillations becomes 5 s. The value of m in kg is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
dividing & squaring 
25m = 9m + 9
so m = 
kg
