Question

write four conditions in which no work is done ​

Answer 1

Explanation:

the two condition when no work is done by force are as follows : when the angle between the displacement and force applied is 90 degree the force applied is perpendicular to the displacement.

1. When the angle between the displacement and force applied is 90 degree i.e the force applied is perpendicular to the displacement.

2. No work is said to be done if there is no change in position or no motion even after application of force.

3when the angle between the displacement of the object and the force

applied is 180 degree

4- when there is no displacement in the object although force is constantly being applied

Answer 2

Answer:

when the angle between the displacement and force applied is 90 degree the force applied is perpendicular to the displacement.
