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

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

$=1579.1N$
