Question

Solve this
A block of mass m is kept on the edge of a horizontal turn table of radius R, which is rotating with constant
angular velocity $\text{ω}$ ( along with the block ) about its axis. If coefficient of friction is $\text{μ}$, find
the friction force between block and table .

Answer 1

Dear student

Since the block of mass m is rotating with the table so the friction force between block and table will be equal to the centrifugal force on block otherwise block will out of the table so

$F=\mu mg=mR{\omega }^2$
