A particle situated between two parallel metal plates carries a charge of 8 × 10⁻¹⁹ C. The potential difference (p.d.) between the plates is 2000 V. A force of 3.2 × 10⁻¹³ N due to the electric field acts on the particle. What is the distance between the plates?

A5 mm

B8 mm

C5 cm

D8 cm

✓ Correct answer

A: 5 mm
