An electric field exists in the space between two charged metal plates. [Figure 31.1] Which graph shows the variation of electric field strength E with distance d from X along the line XY?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
AAn E-d graph showing E starting at a maximum and decreasing exponentially.
BAn E-d graph showing E starting at a maximum and decreasing linearly to zero.
CAn E-d graph showing E constant across the distance d.
DAn E-d graph showing E starting at zero and increasing linearly with d.
✓ Correct answer
C: An E-d graph showing E constant across the distance d.
