A mass of `2.0kg`is put on a that pan attached to a vertical spring fixed on the ground as shown in the figure The mass of the spring and the pen is negligible the mass executing a simple harmonic motion The spring constant is `200N//m` what should be the minimum amplitude of the motion so that the mass get detached from the pan? `(Taking g = 10m//s^(2))`

A

4.0 cm

B

8.0 cm

C

10.0 cm

D

Any value less than 12.0 cm

Text Solution

Verified by Experts

The correct Answer is:
C
For given condition `mg=m omega^(2)a=ka`
`implies a=(mg)/(k)=(2xx10)/(200)=0.1=10cm`
