Q61 / 90 · JEE Main 2012 (26 May Online) · Physics

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

A
B
Correct answer
C
D

Solution

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:

Hence, the correct answer is option: 'C'.
