The centripetal force is #=1579.1N#

The centripetal force is

#F_C=mv^2/r=mromega^2#

The mass of the object is #m=2kg#

The radius is #r=5m#

The frequency of the rotation is #f=2Hz#

The angular velocity is

#omega=2pif=2pi*2=4pi rads^-1#

Therefore, the centripetal force is

#F_C=mromega^2=2*5*(4pi)^2#

#=1579.1N#
