In the diagram, voltmeters P and Q are connected to a potential divider. The sliding connection at point X is moved nearer to the top of the diagram. What change occurs in the reading on P and in the reading on Q?
- Areading on P decreases; reading on Q decreases
- Breading on P decreases; reading on Q increases
- Creading on P increases; reading on Q decreases
- Dreading on P increases; reading on Q increases
