Question

A block of mass m is suspended by a light thread from an elevator. If the elevator is moving upwards what will the value of tension in the string

Answer 1

Hiii. ...friend

Here is ur answer ,

Let assume that, elevator is moving with an acceleration " a ".

So, If the lift with up. The weight of the block inside the lift increases.I.e, apparent weight.

Apparent weight = m (g+a).

If the lift is stationary.Then the tension in the string will be mg.

But the elevator is accelerating. so the tension in the string will be ,

T = m (g+a).

:-)Hope it helps u.
