Question

Two identical metal plates are given positive charges Q1 and Q2 (< Q1 ) respectively. If they are now brought close together to form a parallel plate capacitor with capacitance C, the potential difference between them is

  1. fraction numerator Q subscript 1 plus Q subscript 2 over denominator 2 C end fraction
  2. fraction numerator Q subscript 1 plus Q subscript 2 over denominator C end fraction
  3. fraction numerator Q subscript 1 minus Q subscript 2 over denominator C end fraction
  4. fraction numerator Q subscript 1 minus Q subscript 2 over denominator 2 C end fraction

The correct answer is: fraction numerator Q subscript 1 minus Q subscript 2 over denominator 2 C end fraction
