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

A partical is placed at rest inside a hollow hemisphare of redius R . The coefficient of friction between the partical and the homisphere is mu = (1)/sqrt(3) . The maximum height up to which the partical can remain stationary is

A particle inside a hollow sphere of radius r, having coefficient of friction (1/ √3 ​ ), up to what height can particle be at rest?

Two hemispheres of radii R and r(lt R) are fixed on a horizontal table touching each other (see figure). A uniform rod rests on to spheres as shown. The coefficient of friction between the rod and two spherers is mu . Then the maximum value of the ratio (r)/(R) for which the rod will not slide is :
