Question

Four charges 2 C , -3 C , -4 C and 5 C, respectively, are placed at all the corners of a square. Which of the following statements is true for the point of intersection of the diagonals? (A) Electric field is zero but electric potential is nonzero (B) Electric field is non-zero but electric potential is zero (C) Both electric field and electric potential are zero (D) Neither electric field nor electric potential is zero

V=9 × 109[(2/r)-(3/r)-(4/r)-(5/r)]=0 Electric fields due to all the charges shall not cancel out because of different directions.

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

Electric field is zero but electric potential is nonzero

Electric field is non-zero but electric potential is zero

Both electric field and electric potential are zero

Neither electric field nor electric potential is zero

$V = 9 \times 1 0^{9} [\frac{2}{r} - \frac{3}{r} - \frac{4}{r} - \frac{5}{r}] = 0$
Electric fields due to all the charges shall not cancel out because of different directions.
