An electron moves with a speed of 15x107 ms in the

Question

Part 1. An electron moves with a speed of 1.5x10⁷ m/s in the directions shown in (Figure 1) below. A 0.30 T magnetic field points in the positive x-direction.

A) What is the magnitude of the magnetic force in figure (a)?

B) What is the magnitude of the magnetic force in figure (b)?

Part 2. A uniform 2.5 T magnetic field points to the right. A 3.0-m-long wire, carrying 15 A, is placed at an angle of 30^o to the field, as shown in the figure.(Figure 1)

A) What is the magnitude of the force on the wire?

B) What is the direction of the force on the wire?
