Consider two identical charges placed a distance `2 d` apart on the `x`-axis.The equilibrium of a positive test charge placed at the point `O` midway between them may be (i) neutral (ii) stable for displacement along the `x`-axis (iii) stable for displacement along the `y`-axis (iv) unstable for displacement along the `x`-axisA. stable for displacements along the x-axisB. neutralC. unstable for displacement along the y-axis.D. stable for displacements along the y-axis

Answer» Correct Answer - A::C
a.,c.
If positive test charge is displaced along `x-`exis, then net force will always act in a direction opposite to that of displacement and the test charge will always come back to its original position. But if test charge is displaced along `y-` exis, if will never come back to its original position and will fly away along `y-`axis.
