Question
One end of a string of length l is connected to a particle of mass m and the other to a small peg on a smooth horizontal table. If the particle moves in a circle with speed v the net force on the particle (directed towards the centre) is :
Options
A.T
B.$T - \frac{mv^{2}}{\mathcal{l}}$
C.$T + \frac{mv^{2}}{\mathcal{l}}$
D.0
Solution
Sol.
Due to radial acceleration only one force acting towards the centre which is Tension.
(A) T
