Mass $m = 5 k g$ $m = 5kg$
frequency of rotation $n = 5 H z$ $n =5Hz$
Radius of circular path $r = 3 m$ $r = 3m$
Angular velocity $w = 2 π \times n = 10 π \frac{r a d}{s}$ $w = 2pixxn=10pi(rad)/s$
Centripetal force $= m w^{2} r = 5 \times 100 π^{2} \times 3 = 1500 π^{2} N$ $=mw^2r=5xx100pi^2xx3=1500pi^2N$
