Two parallel metal plates are connected to a battery of negligible internal resistance. [Figure 32.1] One of the plates is slowly moved towards the other. Which row is correct?
Aelectric field strength between the plates: decreases, potential difference between the plates: constant
Belectric field strength between the plates: increases, potential difference between the plates: constant
Celectric field strength between the plates: decreases, potential difference between the plates: increases
Delectric field strength between the plates: increases, potential difference between the plates: increases
