Question

Figure shows a system of three positive charges placed at the vertices of an equilateral triangle. To decrease the potential energy of the system, (A) a positive charge should be placed at centroid. (B) a negative charge should be placed at centroid. (C) distance between the charges should be decreased. (D) it should be rotated by an angle of (π/2) radian.

Potential energy decreases whenever there is attraction. A negative charge placed at centroid causes attraction

Q. Figure shows a system of three positive charges placed at the vertices of an equilateral triangle. To decrease the potential energy of the system,

a positive charge should be placed at centroid.

a negative charge should be placed at centroid.

distance between the charges should be decreased.

it should be rotated by an angle of $\frac{π}{2}$ radian.

Potential energy decreases whenever there is attraction. $A$ negative charge placed at centroid causes attraction
