A charge Q1\mathrm{Q}_{1} exerts some force on a second charge Q2\mathrm{Q}_{2}. If a 3 rd charge Q3\mathrm{Q}_{3} is brought near, then the force of Q1\mathrm{Q}_{1} exerted on Q2−\mathrm{Q}_{2}-

Options

  1. Awill increase
  2. Bwill decrease
  3. Cwill remain unchanged
  4. Dwill increase if Q3\mathrm{Q}_{3} is of the same sign as Q1\mathrm{Q}_{1} and will decrease if Q3\mathrm{Q}_{3} is of opposite sign.

Correct answer

C. will remain unchanged
