Answer:

The centripetal force is #=20213N#

Explanation:

The centripetal force is

#F=mromega^2#

The mass of the object is #m=4kg#

The radius of the circle is #r=2m#

The frequency is #f=8Hz#

The angular velocity is #omega=2pif=2*pi*8=16pirads^-1#

The centripetal force is

#F=4*2*(16pi)^2=20213N#
