Question 135 of 311

Three positive charges of equal value qq are placed at vertices of an equilateral triangle. The resulting lines of force should be sketched as in

Show answer and solution

Answer: (C)

Electric lines of force due to a positive charge is spherically symmetric.
All the charges are positive and equal in magnitude. So repulsion takes place. Due to which no lines of force are present inside the equilateral triangle and the resulting lines of force obtained as shown:
