Explanation / Answer

We need the two magnetic force components

F = qvB

F = (38 X 10-6)(74)(.41)

F = 1.153 X 10-3 N in positive z direction

Then

F = qvB

F = (38 X 10-6)(74)(.84)

F = 2.36 X 10-3 N in the negative y direction

The net is from the Pythagorean theorem

Net2 = (1.153 X 10-3)2 + (2.36 X 10-3)2

Net = 2.6 mN

Part B)

For the angle...

tan(angle) = 2.36 X 10-3/1.153 X 10-3

angle = 64o
