A child of mass 5 kg is going round a merry-go-round that makes 1 rotation in 3.14 s. The radius of the merry-go-round is 2 m. The centrifugal force on the child will be
Text Solution
Verified by ExpertsThe correct answer is:
B
The angular speed ( 
) of the child can be calculated as follows:
=2 rad s -1
The formula to calculate the centrifugal force on the child is given by
F r = m 
2 r ...
Substitute the values of the known parameters into equation to calculate the required centrifugal force.
F r =5 kg x (2 rad s -1 ) 2 x 2 m
=40 N
