Question

What are the effects if force is acting on a moving body in a
direction perpendicular to the direction of motion?
(a) The speed changes uniformly
(b) The acceleration changes uniformly
(c) The direction of motion changes
(d) All of these​

Answer 1

It will have no effect on the moving object, as.....

Work done= Force*velocity*costheta

here,

costheta = 90°= 0

So the work done will be zero.....

Please mark me the brainliest...

Hope you find it helpful.
