Question

A mass of 8g is hung to a spring balance in the lift. what is the reading if the lift is moving with an acceleration of g/4

Answer 1

Answer:

-0.0195N or 0.0195N in the opp. direction of the lift acceleration.

Explanation:

Here, g= -9.8m/s² because the motion of gravity is opp. the motion of lift or you can say psuedo acceleration on the mass m due to relative motion of lift.

Hope u get it..
