Magnetism Related Questions,

    Magnetism Related Questions, Please Help!

    There are three questions that I need help with, all of which are focused on the main topic of Magnetism (The Magnetic Force on Moving Charges). Before I begin, I would just like to thank anyone that will be able to provide me with some assistance in answering the following questions.

    1. A negatively charged ion moves due north with a speed of 1.5 x 10^6 m/s at the Earth's Equator. What is the Magnetic force exerted on this ion?

    2. An electron moving with a speed of 9.1 x 10^5 m/s in the positive x direction experiences zero magnetic force. When it moves in the positive y direction it experiences a force of 2.0 x 10^-13 N that points in the negative z direction. What is the direction and magnitude of the magnetic field?

    3. A 5.60 x 10^-6 C particle moves through a region of space where an electric field of magnitude 1250 N/C points in the positive x direction, and a magnitude 1.02T points in the positive z direction. If the net force acting on the particle is 6.23 x 10^-3 N in the positive x direction, find the magnitude and direction of the particle velocity.

    Just to reiterate, I would prefer if someone were to explain to me how I would go about answering each of the questions; I would also like to thank you all one again for any assistance provided in advance.
