1. ### Magnetic/ electric/ gravitational field?

Ah, now I get it. Thanks for the clarification!
2. ### 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...
3. ### 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?
4. ### Current through resistor parallel to two different batteries

Thank you for clarifying. I'll see if I've misunderstood somewhere.
5. ### 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...
