The centripetal force is #=4974.3N#

The centripetal force is

#F=mromega^2#

The mass of the object is

#m=2kg#

The radius of the circle is

#r=7m#

The frequency of rotation is

#f=3Hz#

The angular velocity is

#omega=2pif=2*pi*3=6pirads^-1#

Therefore,

the centripetal force is

#F=2*7*(6pi)^2=4974.3N#
