A body is under the action of a force 5 newton moves through 10 m in a straight line. If work done is 25 joule, what is the angle at which force acts with the direction of motion ?

A

Zero

B

`30^(@)`

C

`90^(@)`

D

`60^(@)`

Text Solution

Verified by Experts

The correct Answer is:
d

`W=FS cos theta implies 25xx5xx10 cos theta`.
`cos theta=1/2 implies theta=60^(@)`
