What is the magnitude of magnetic force per unit length on a wire carrying a current of 8 A and making an angle of 30º with the direction of a uniform magnetic field of 0.15 T?

The current going through the wire (I) is 8 A.

The uniform magnetic field (B) has a magnitude of 0.15 T.

The angle between the wire and the magnetic field is 

We know, magnetic force per unit length on the wire is

So, the magnetic force per unit length on the wire is
