If the lift is moving upwards with a uniform velocity then the frictional resistance offered by the body is(assume the assume of body as m)

Question

If the lift is moving upwards with a uniform velocity then the frictional resistance offered by the body is-assume the assume of body as m-mgmu mg02mg

Toppr Admin · Accepted Answer

For motion of the lift with uniform velocity,
$R = m g$ , because the acceleration is zero.
The frictional force acts opposite to the direction hence μR = μmg
or frictional resistance = μmg

If the lift is moving upwards with a uniform velocity then the frictional resistance offered by the body is(assume the assume of body as m)mgμmg02mg

For motion of the lift with uniform velocity,R=mg, because the acceleration is zero. The frictional force acts opposite to the direction hence μR = μmgor frictional resistance = μmg
