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

Options

  1. AR 2
  2. B(1- 3 2 ) R
  3. C3 2 R
  4. D3R 8

Correct answer

B. (1- 3 2 ) R

Step-by-step solution

Using h_ = (1- 1 ^2+1 ) R aligned & = (1- 1 ( 1 3 )^2+1 ) R ( = 1 3 ) & = (1- 1 1 3 +1 ) R= (1- 1 1+3 3 ) R & or, h_ = (1- 3 2 ) R aligned
