One end of string of length `l` is connected to a particle on mass `m` and the other end is connected to a small peg on a smooth horizontal table. If the particle moves in circle with speed `v` the net force on the particle (directed toward centre) will be (`T` reprents the tension in the string):

Options

A. `T + (mv^(2))/(1)`
B. `T - (mv^(2))/(1)`
C. zero
D. `T`

Explanation

Net force toward centre is `T`
`T = (mv^(2))/(l)`
