Question
One end of string of length l is connected to a particle of 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 towards centre) will be (T represents the tension in the string) :-
Options
A.
B.
C.
Zero
D.
T
Solution
Net force on the particle in uniform circular motion is centripetal force, which is provided by the tension in string.
