A current carrying wire LN is bent in the form shown below. If wire carries a current of 10 A and it is placed in a magnetic field of 5T which acts perpendicular to the paper outwards then it will experience a force

A

Zero

B

5 N

C

30 N

D

20 N

Text Solution

Verified by Experts

The correct Answer is:
B
We can replace bent wire as straight wire
`vecF = i(L xx B) " " (because L = int` idl)
F = Bil
`= 5 xx 10 xx 0.1`
`= 5 N`
