Answer:
The work done by gravity is 784 J.
Explanation:
Given:
Mass of the block is,
Height to which it is raised is,
Acceleration due to gravity is,
Now, work done by gravity is equal to the product of force of gravity and the distance moved in the direction of gravity. So,
Force of gravity is given as the product of mass and acceleration due to gravity.
. Now,
Therefore, the work done by gravity is 784 J.
