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

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