Question

5. A mass of 10 kg is at a point A on a table. It is moved to a point
B. If the line joining A and B is horizontal, what is the work
done on the object by the gravitational force? Explain your
answer.​

Answer 1

Answer:

It is moved to a point B. If the line joining A and B is horizontal, what is the work done on the object by the gravitational force? Hence, the work done by gravity on the body is zero

Answer 2

Answer:

${\tt{\blue{\bold{\huge{Question}}}}}$

A mass of 10 kg is at a point A on a table. It is moved to a point B. If the line joining A and B is horizontal, what is the work done on the object by the gravitational force? Explain your answer.

${\tt{\pink{\bold{\huge{Answer}}}}}$

The work done is zero. This is because the gravitational force and displacement are perpendicular to each other.
