I have multiple choice questions, but I only get one chance, so I want to make sure I answer correctly.
1. A charged rod is brought near a suspended object, which is attracted to the rod. Can we conclude that the suspended object is charged? Explain.
o Yes
o No
Yes, the suspended object is negatively charged.
2. A proton moves in a region of constant electric field. Does it follow that the proton's velocity is parallel to the electric field?
o Yes
o No
No, it moves in the opposite direction.
Does it follow that the proton's acceleration is parallel to the electric field? Explain.
o Yes
o No
I am not sure in this case.
