The centripetal force is $= 13817.4 N$ $=13817.4N$

The centripetal force is

$F = m r ω^{2}$ $F=mromega^2$

The mass of the object is $m = 2 k g$ $m=2kg$

The radius of the circle is $r = 7 m$ $r=7m$

The frequency is $f = 5 H z$ $f=5Hz$

The angular velocity is $ω = 2 π f = 2 \cdot π \cdot 5 = 10 π r a d s^{- 1}$ $omega=2pif=2*pi*5=10pirads^-1$

The centripetal force is

$F = 2 \cdot 7 \cdot {(10 π)}^{2} = 13817.4 N$ $F=2*7*(10pi)^2=13817.4N$
