Vedclass · Answer

(B) Let the side of the square be $a$. The distance from each corner to the center (intersection of diagonals) is $r = \frac{a}{\sqrt{2}}$.Electric potential $V$ at the center is the algebraic sum of potentials due to individual charges: $V = \frac{k}{r} (q_1 + q_2 + q_3 + q_4) = \frac{k}{r} (2 - 3 - 4 + 5) = \frac{k}{r} (0) = 0$.Electric field $E$ is a vector quantity. The electric field vectors from the charges at the center do not cancel each other out because the charges are not equal and opposite in pairs. Specifically,the field vectors from $2C$ and $-4C$ do not cancel,nor do those from $-3C$ and $5C$. Thus,the net electric field $E 
eq 0$.Therefore,the electric field is non-zero,but the electric potential is zero.

Four charges $2C, -3C, -4C$ and $5C$ are placed at the corners of a square. Which of the following statements is true for the point of intersection of the diagonals?
