A particle of mass ' $m$ ' is rotating along a circular path of radius ' $r$ ' having angular momentum ' $L$ '. The centripetal force acting on the particle is given by

Options:

Answer:

Solution:

$∴ ∴ Centripetal force = m ω^{2} r ω = \frac{L}{I} = \frac{L}{m r ^{2}} \dots (∵ L = I ω) F = m (\frac{L}{m r ^{2}})^{2} r = \frac{m ^{2} r}{m ^{2} r ^{4}} = \frac{L ^{2}}{m r ^{3}}$
