    Answer:

    67.5

    Explanation:

    F= BILsin\theta where F is the magnitude of the force, B is the magnetic field, I is current, \theta is the angle of inclination, L is the length of the wire.

    Substituting 0.9 T for magnetic field B, 10 m for length, 15 A for current I and 30 degrees for \theta then

    F=0.9\times 15\times 10\times sin 30^{\circ}=67.5
