Two parallel metal plates have a potential difference between them of 12 V. The distance between the plates is 1.0 mm. What are the electric field strength between the plates and the work done on a charge of +3.9 μC to move the charge from the negative plate to the positive plate?
Aelectric field strength/N C⁻¹: 12, work done /J: 4.7 x 10⁻⁵
Belectric field strength/N C⁻¹: 12, work done /J: 47
Celectric field strength/N C⁻¹: 12000, work done /J: 4.7 x 10⁻⁵
Delectric field strength/N C⁻¹: 12000, work done /J: 47
✓ Correct answer
C: electric field strength/N C⁻¹: 12000, work done /J: 4.7 x 10⁻⁵
