A particle of mass $200 \,g$ is moving in a circle of radius $2 \,m$. The particle is just 'looping the loop'. The speed of the particle and the tension in the string at highest point of the circular path are $\left(g=10 \,ms ^{-2}\right)$

A$4 \,ms ^{-1}, 5 \,N$

B$4.47 \,ms ^{-1}$, zero

C$2.47 \,ms ^{-1}$, zero

D$1 \,ms ^{-1}$, zero

Solution

(b)
$V=\sqrt{g L}=4.47 \,m / s$
$T=0$
