Electric intensity at the centre of a uniformly distributed charge is:
Correct answer: A. Zero
- A. Zero
- B. Kq/r2
- C. q/r2
- D. q/e0
Explanation
The electric intensity at the center of a uniformly distributed charge depends on the charge distribution and the geometry of the system. If you are referring to a spherically symmetric charge distribution, such as a uniformly charged sphere, the electric field intensity at the center is zero. This is because the electric field vectors from all points on the sphere cancel each other out due to the symmetry of the distribution.Hence, A is the correct option.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
