A Body moves a distance of 10 m along a straight line under the action of a force of 5N.if the work done is 25 joules the angle which the force makes with the direction of motion of the body is

A

`0^@`

B

`30^@`

C

`60^@`

D

`90^@`

Text Solution

Verified by Experts

The correct Answer is:
C
`W = FS cos theta`
`= cos theta =W/(FS) = 25/50 =1/2 implies theta = 60^@`
