Take CBT

Question

A proton and an electron are released from rest 1 meter apart. Where would they meet?
Options
A Exactly in the middle at 0.5 m.
B Closer to the electron's original position.
C Closer to the proton's original position.
Correct Answer
D They would move away and never meet.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Because the proton is much more massive than the electron, the same force produces a much smaller acceleration for the proton. The electron covers most of the distance.

Hint

F = ma; think about mass differences.
