    Magnetic/ electric/ gravitational field?

    Yes, the particle is charged, but not exactly massive. Let's assume that it is a point charge. It's not specified whether is + or - In electrical and magnetic field, force will act on a charged particle as long as it is not perpendicular to the field. Which leaves only gravitational field. But...

    Magnetic/ electric/ gravitational field?

    I got a question from my exam. We are given the name of three fields; electric field, magnetic field and gravitational field. A charged particle is placed in a field, but no force will act on it if it's stationary or moving in any direction. What field is the particle placed in?

    Current through resistor parallel to two different batteries

    Homework Statement I'm sorry that I have no pic, but please bear with my description. The circuit diagram is made up of 3 horizontal lines. On the top line, there's battery A, (-) on the left, (+) on the right, and an arrow going to the right (>) to show direction of current. On the...
