Answer:

The centripetal force is #=13817.4N#

Explanation:

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 is #f=5Hz#

The angular velocity is #omega=2pif=2*pi*5=10pirads^-1#

The centripetal force is

#F=2*7*(10pi)^2=13817.4N#
