A conductor of length 5 m and carrying current of 2 A is kept inclined at `30^(@)` to a uniform magnetic field of induction `0.4` tesla. What is the force acting on the conductor ?

A

5 N

B

4 N

C

3N

D

2 N

Text Solution

Verified by Experts

The correct Answer is:
D
`l=5 m, I =2A, B=0.4T, theta=30^(@)`
`F =BI l sin theta =0.4 xx2xx5xxsin 30^(@) =4 xx1/2=2`
`therefore F =2` newtion
