STANDARD Physics Electric Field and Potential MCQ Question
Type: MCQ-conceptual-Medium
Two charges q and –3q are fixed on x-axis separated by distance d. Where should a third charge 2q be placed from A such that it will not experience any force?
A
(d - √3d) / 2
B
(d + √3d) / 2
C
(d + 3d) / 2
D
(d - 3d) / 2
Correct Answer
Option B
Detailed Explanation
To find the position where the third charge 2q experiences no net force, we set the forces due to q and -3q equal in magnitude. Solving the equation gives the position as (d + √3d) / 2.
