Physics · Class 12 · CBSE — Electric Charges and Fields
Two identical point charges are placed at the two vertices \(A\) and \(B\) of an equilateral triangle of side \(l\) . The magnitude of the electric field at the third vertex P is E. If a hollow conducting sphere of radius ( \(l / 4\) ) is placed at P, the magnitude of the electric field at point P now becomes
- \(\gt {E}\)
- E
- \(\frac{{E}}{2}\)
- zero
Answer
(D) zero
