The centripetal force is #=25266.2N#

The centripetal force is

#F=mromega^2#

The mass of the object is

#m=5kg#

The radius of the circle is

#r=8m#

The frequency of rotation is

#f=4Hz#

The angular velocity is

#omega=2pif=2*pi*4=8pirads^-1#

Therefore,

the centripetal force is

#F=5*8*(8pi)^2=25266.2N#
