The centripetal force is $=213183.5N$

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

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