Kinematics Question 776
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}} $
