The centripetal force is #=213183.5N#

Explanation:

The centripetal force is

#F=mromega^2#

The mass of the object is

#m=6kg#

The radius of the circle is

#r=4m#

The frequency of rotation is

#f=15Hz#

The angular velocity is

#omega=2pif=2*pi*15=30pirads^-1#

Therefore,

the centripetal force is

#F=6*4*(30pi)^2=213183.5N#
