Three charges each of +1 C are placed at the corners of an equilateral triangle. If the repulsive force between any two charges is F , then the net force on either charge will be

Options

  1. A2 ~F
  2. B3 ~F
  3. C2 ~F
  4. D3 ~F

Correct answer

D. 3 ~F

Step-by-step solution

The force on any charge due to each of the other two charges has magnitude F . The angle between the two forces is 60^ . Hence the resultant force is given by R= F^2+F^2+2 F^2 60^ = 3 F
