A force of 5 N, making an angle `theta` with the horizontal, actig on an object displaces it by 0.4 m along the horizontal direction. If the object gains kinetic energy of 1J. The horizontal component of the force is

A

1.5 N

B

2.5 N

C

3.5 N

D

4.5 N

Text Solution

Verified by Experts

The correct Answer is:
B
`W = Deltak implies FS cos theta = 1implies F cos theta =1/S =1/(0.4) = 2.5 N`
