Question

A block of mass 10 kg is in contact against the
inner wall of a hollow cylindrical drum of
radius 1 m. The coefficient of friction between
the block and the inner wall of the cylinder is
0.1. The minimum angular velocity needed for
the cylinder to keep the block stationary when
the cylinder is vertical and rotating about its
axis, will be ?

Answer 2

Hey mate....

here's the answer

A block of mass 10 kg is in contact against the

inner wall of a hollow cylindrical drum of

radius 1 m. The coefficient of friction between

the block and the inner wall of the cylinder is

0.1. The minimum angular velocity needed for

the cylinder to keep the block stationary when

the cylinder is vertical and rotating about its

axis, will be ?

w(min)= √g/ru

w(min)= √10/0.1 x 1

= 10 rad/S

Hope this helps❤
