A particle is placed at rest inside a hollow hemisphere of radius 'R'. The co-efficient of friction between the particle and the hemisphere is mu =(1)/(sqrt(3)). The maximum height upto which the particle can remain stationary is

A particle is placed at rest inside a hollow hemisphere of radius 'R'.

1.	A particle is placed at rest inside a hollow hemisphere of radius 'R'. The co-efficient of friction between the particle and the hemisphere is mu =(1)/(sqrt(3)). The maximum height upto which the particle can remain stationary is
Answer» `(R )/(2)` `(1-(SQRT(3))/(2))R` `(sqrt(3))/(2)R` `(3R)/(8)` ANSWER :B
