Two vertical conducting plates X and Y are positioned so that they are separated by a distance of 6.0 mm in air. A 60 V d.c. supply is connected as shown. [Figure 31.1] What is the electric field strength at E, a point midway between the plates?

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.

A1.0 × 10⁴ V m⁻¹ towards X

B1.0 × 10⁴ V m⁻¹ towards Y

C2.0 × 10⁴ V m⁻¹ towards X

D2.0 × 10⁴ V m⁻¹ towards Y

✓ Correct answer

B: 1.0 × 10⁴ V m⁻¹ towards Y
