A particle of mass m is tied to a light string and rotated with a speed v along a circular path of radius r. If T = tension in the string and mg = gravitational force on the particle then the actual forces acting on the particle are
Text Solution
Verified by ExpertsThe correct answer is:
A
The force mv 2 /r directed outwards, called centrifugal force, is not a real force
At A, mv 1 2 /l = T 1 + mg.
