Physics Two Dimensional Motion Question 280
Question: A particle of mass $ m $ is executing uniform circular motion on a path of radius $ r $ . If $ p $ is the magnitude of its linear momentum. The radial force acting on the particle is
[MP PET 1994]
Options:
A) $ pmr $ B) $ \frac{rm}{p} $ C) $ \frac{mp^{2}}{r} $ D) $ \frac{p^{2}}{rm} $
Show Answer
Answer:
Correct Answer: D
Solution:
Radial force $ =\frac{mv^{2}}{r}=\frac{m}{r}{{( \frac{p}{m} )}^{2}}=\frac{p^{2}}{mr} $ [As p = mv]
