Question

a 2kg body suspended from a spring of negligible mass is found to streach the spring by 0.1 m if the body is pulled down and the released what is the frequency of the oscillation ​

Answer 1

Answer:

From formula 1, we can say

T=2πkM ...(1)

Also,

35T=2πkM+m ...(2)

Dividing eqn 2 and 1, we get

35=MM+m

∴925=MM+m

∴925=1+Mm

Hence, answer=16/9, i.e. option B
