Question

A 2 kg mass lying on a table is displaced in the
horizontal direction through 50 cm. The work done
by the normal reaction will be ?

Please answer this question as soon as possible and don't go for points or else i will report.
​

Answer 1

Answer: 0

Explanation:

Normal reaction on the-mass by the table is perpendicular to the horizontal displacement. Hence work done by normal reaction will be zero.

Answer 2

Answer:

The work done by the normal reaction will be zero.

Explanation:

Normal reaction a bouncing back force acting at straight angle as a result of action reaction forces.

For an object kept on a table or surface, it acts perpendicular to the horizontal or the surface or the table.

We know that, forces acting at right angles ultimately tend to be zero for their effect in horizontal axis.

Hence, the work done by the normal in the given case will be zero.
