Question

A particle is placed at rest inside a hollow hemisphere of radius R. The coefficient of friction between the particle and the hemisphere is = 1 3. The maximum height upto which the particle can remain stationary is

Accepted Answer

Correct answer: B. (b) Usingh_ max=(1- 1 ^2+1)R =(1- 1 ( 1 3 )^2+1) R ( ∵ = 1 3) =(1- 1 13+1) R=(1- 1 1+33) R h_ max=(1- 32)R

$A particle is placed at rest inside a hollow hemisphere of radius R . The coefficient of friction between the particle and the hemisphere is μ = \frac{1}{3} . The maximum height upto which the particle can remain stationary is$
