A horizontal magnetic field of 17times104t is at an angle

Question

Solve the all parts of given problem below:

Problem: A horizontal magnetic field of 1.7×10⁴T is at an angle of 34 degree to the direction of the current in a straight, horizontal wire 75cm long.

Part a: If the wire carries a current of 16A, what is the magnitude of the force on the wire?

Part b: What angle(s) would be required for the force to be half the value found in part A, assuming nothing else is changed?

Please show how you obtained the answer.
