CHALLENGING ELECTROSTATICS QUESTIONS NEET JEE
1. A non-conducting solid sphere of radius R has a uniform charge density ρ. Calculate the electric potential at a point P located at a distance d from the center of the sphere, outside the sphere. 2. Two point charges, +q and -q, are placed a distance d apart. Find the electric field at a point P along the perpendicular bisector of the line joining the charges. 3. Three point charges q1, q2, and q3 are placed at the corners of an equilateral triangle of side length a. Find the electric field and potential at the center of the triangle. 4. Three point charges +Q, +2Q, and -3Q are placed at the vertices of an equilateral triangle. What is the net electric field at the centroid of the triangle? a) Zero b) Non-zero but not determinable c) Parallel to one of the sides of the triangle d) Perpendicular to one of the sides of the triangle 5. A spherical shell of radius R carries a uniformly distributed positive charge Q. What is the electric field inside the shell? a)...
