Vedclass · Answer

(A) For a system of point charges to be in equilibrium, the net electrostatic force on each individual charge must be zero.In an equilateral triangle, the forces exerted by any two charges on the third charge are directed along the sides of the triangle.Since these forces are vectors acting at $60^{\circ}$ to each other, their resultant can only be zero if the charges are such that the vector sum of forces is zero.However, for three point charges at the vertices of an equilateral triangle, it is mathematically impossible for the net force on all three charges to be zero simultaneously, regardless of the magnitudes or signs of the charges.Therefore, the system can never be in equilibrium under the influence of electrostatic forces alone.

Three point charges are placed at the corners of an equilateral triangle. Assuming only electrostatic forces are acting, which of the following statements is true?
