An electron with a speed of 3.5 x 107 m/s travels upwards into a 3.0 T magnetic field directed into the page. After the particle is deflect it enters a circular path. What direction is the particle deflected? What is the radius of the circular path the electron travels through? Include a diagram.
A 20.0 m long wire is carrying a 150.0 mA current parallel to a second wire that is extremely long which carries a current of 250.0 mA in the same direction. These wires are placed 40.0 cm apart in a 5.5 T magnetic field that is directed into the page.. Calculate the magnetic force on each wire and indicate the direction of the force. Each of these wires would generate a smaller magnetic field, indicate the direction this magnetic field would travel between the wires.

A ball, mass m1 = 0.1 kg, is moving upwards with a speed of 10
m/s when it collides inelastically with a cup, mass m2 = 0.9 kg,
that is initially at rest. After the collision the system
(ball+cup) moves straight upwards without rotating. This collision
occurs on Earth, and the local gravitational field points down with
g = 9.8 m/s2 .
(a) What is the momentum of the system before the collision?
