Question
a person stands in contact against the inner wall of a rotor of radius r. The coefficient of friction between the wall and the clothing is μ and the rotor is rotating about vertical axis. The minimum speed of the rotor so that the person does not slip downward is
1. √μg/r 2. √g/μr
Read 1 Solution.
mv2/r = R (horizontly)
f = mg (vertically)
mg = µR
mg = µ mv2/r
v = √gr/µ
here ans is not matching becoz u have given dimentionally incorrect optn check optn is not of velocity
