Question: A particle of mass M moves with constant speed along a circular path of radius r under the action of a force F. it’s speed is[MP PMT 2002]

Options:

A) $ \sqrt{\frac{rF}{m}} $

B) $ \sqrt{\frac{F}{r}} $

C) $ \sqrt{Fmr} $

D)$ \sqrt{\frac{F}{mr}} $

Show Answer

Answer:

Correct Answer: A

Solution:

$ F=\frac{mv^{2}}{r} $

therefore $ v=\sqrt{\frac{rF}{m}} $
