Physics Fundamentals : CRO and Potential Divider

1. The problem statement, all variables and given/known data

The figure shows 2 terminals M and N of a potential divider connected to a 6V battery. The circuit is connected to a Cathode-ray Oscillator.

(a) Describe in details what happens as the terminal is moved at a uniform speed from N to M.
(b) Draw the final reading of the final trace that is shown the CRO as N is moving towards M.

2. Relevant equations

None

3. The attempt at a solution

(a) As terminal N is moving towards M, there will be an increased in e.m.f, the results in a higher reading on the tracd

(b) http://ift.tt/1oi9SB4
This is my attempt.

Please correct me if I make any mistakes. Thank you!
