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

    Attached in picture

    2. Relevant equations

    N/A

    3. The attempt at a solution

    for What will happen if you cut the wire at position B?

    I think The light bulb will become dimmer, but not go off. Am I correct?

    for What will happen if you cut the wire at position D?

    I think The light bulb will go off. (since the bulb was disconnected from the circuit) Am I correct?

    The light bulb? Are we talking about the bulb that the hand is pointing to? If so, then you are right.

    Correct.

    I would be interested in your reasoning for the globe dimming when the wire is cur at B. You may have just made a lucky guess.
