JEE Main Physics question
One end of a string of length is fixed to a small peg on a smooth horizontal table and the other end is tied to a particle of mass , which moves in a circle with speed . The net force on the particle (directed toward the centre) is
Answer: (A)
Solution
On the smooth table the only horizontal force on the particle is the string tension , which alone supplies the centripetal force
