Question

A lift is going down with the acceleration of g/2. A man is inside of the left and his mass is m what will be the reaction of the floor on the man​

Answer 1

Given :

Mass of man = m

Lift is going down with the acceleration of g/2$.$

To Find :

We have to find reaction of the floor on the man$.$

SoluTion :

The reaction force exerted by floor on the man in a lift, when the lift moves downward with acceleration a is given by

• R = m(g - a)

፨ Negative sign shows that, Pseudo force acts in the opposite direction.

⇒ R = m(g - a)

⇒ R = m(g - g/2)

⇒ R = mg/2 ☃
