Homework Help: Physics - electrons/protons

Posted by Mary on Sunday, October 4, 2009 at 6:44pm.

If you place a free electron and a free proton in the same electric field, how do the forces acting on them compare? How do their accelerations compare? Their directions of travel?

My answer: Direction of travel: The proton and electron would move towards each other, as the electron carries a negative charge, the proton a positive charge, and opposite charges attract.

How forces compare: I would assume the forces would be the same, since forces that act upon each other are equal.

But I am not sure about how their accelerations compare. How do they compare, and are my other two answers correct?
