Question

A wire segment 2.4m long carries a current of 7A and makes an angle of 40º with positive y axis in a region where the magnetic field is uniform and given by B = 0.5T in positive x-direction. What is the resulting magnetic force on the wire in S.I units?

Answer 1

Diagram to understand the question is-

Given in the question-

I=7A

Now, we know that the formula of magnetic force is-  

  

Hence, putting the above values in it, we get-

, since

, since

,

hence-
