Eletric and Magnetic Fields?

The choices are either yes or no for each question.

Assume the motions and currents mentioned are along the x axis and fields are in the y direction.

(a) Does an electric field exert a force on a stationary charged object?

i assume this is yes

(b) Does a magnetic field do so?

Pretty sure this is no, correct me if i'm wrong

(c) Does an electric field exert a force on a moving charged object?

think it's yes

(d) Does a magnetic field do so?

also yes?

(e) Does an electric field exert a force on a straight current-carrying wire?

Yes?

(f) Does a magnetic field do so?

Yes?

(g) Does an electric field exert a force on a beam of moving electrons?

Not sure

(h) Does a magnetic field do so?

not sure

All of my answers are just based on thinking about it, i have no real reason why, so any explaination would be greatly appreciated

Thanks in advance
