A small body of mass 100 g is undergoing SHM of amplitude 100 cm and period 0.2 s. What is the maximum value of the force acting on the body ?

A

86.4 N

B

102.1 N

C

98.5 N

D

71.2 N

Text Solution

Verified by Experts

The correct Answer is:
B
Maximum force
`F=masquare^(2)=["mass"xx"maximum acceleration"]`
`F=ms((2pi)/(T))=(4pi^(2)ma)/(T^(2))`
`F=(4xx(3.14)^(2)xx0.1xx1)/((0.20)^(2))=(4xx9.85xx0.1xx1)/((0.04)^(2))`
`F=(3.94)/(0.04) =98.5N`
