Answer:
Answer: No work is said to be done when an object moves at an angle of 90 degree with the direction of force.
Explanation:
ANSWER
No work is said to be done when an object moves at an angle of 90 degree with the direction of force.
For eg:- If a waiter catches a ray with one hand in horizontal position, in this case the force supplied by the waiter is an upward force and the displacement of the tray is a horizontal displacement. Thus the angle between them will be 90 degrees. If we calculate the work done it will be zero as Cos90 degree is zero.
Hence when force vector and displacement vector are perpendicular to each other no work is siad to be done.
