Question

(work)
A string is used to pull a block of mass m vertically
up by a distance h at a constant acceleration g/3.
The work done by the tension in the string

(1) 2/3mgh
(2)-mgh/3
(3)mgh
(4)4/3mgh​

Answer 1

Answer:

Explanation:

T= m( g+a)

=m ( g+g/3)

T= 4mg/3

workdone = Tension × Distance

= 4mg/3×h

= 4mgh/ 3

Answer 2

your answer will be -mgh/3

hope this helps you
