Question

what happens to the work done when the displacement of a body is at right angles to the direction of force acting on it explain your answer​

Answer 1

Answer:

The work done by the body = 0

Step-by-step explanation:

WORK = f. Cos thetha.S

Where f= force and

S= displacement

Explanation 1 ( Mathematical)

Cos90= 0 according to trigonometric ratio of thetha

Since WORK = f. Cos thetha.S

Therefore if Cos thetha = 0

Then WORK = f. 0. S = 0

Answer 2

Answer:

The work done by the body is 0

Step-by-step explanation:

since theta = 90° and cos(90°)= 0, this means that there is 0 joules of work done by the force since displacement is at a right angle to the force applied.
