Answer 1

Answer:

Explanation:

Answer:

T= m ( g+a)

Explanation:

Given that

mass= m

Lets take up ward acceleration of the elevator is a m/s²

From second law of Newtons

F(net) = m a

Lets take tension in the string is T

T- m g = m a

T= m g + m a

T= m ( g+a)

So we can say that when object will move upward then tension in the spring will be more as compare to when object is in rest.

When object move downward then tension T

T= m (a - g)
