Question

A body of mass 4 kg weigh 4.8kg whwn suspended in a moving lift.The acceleration of lift is

Answer 1

W=ma

4.8=4*a

a=4.8/4

a=1.2m/s2

weight is increasing. so it is moving upwards.

therefore (d) is correct

Hope it helps :)

Answer 2

Hey there!

Given,

Mass (m) = 4 kg

Weight (w) = 4.8 kg

We know,

Weight = mass * acceleration due to gravity

4.8 = 4 * a

a = 4.8/4

a = 1.2 m/s²    ←(Answer)
