point charge meaning in Hindi

Examples

1. Conversely, a charge distribution can be approximated by many small point charges.
2. Point particles with electric charge are referred to as point charges.
3. However, this is only the potential for one point charge due to another.
4. This principle is useful to calculate the field created by multiple point charges.
5. For example, consider the electric field arising from a single, isolated point charge.
6. We now introduce a fixed point charge " Q " at the origin.
7. The " relativistically-correct " electric field of a point charge varies with velocity as:
8. Electrons and nuclei are, to a very good approximation, point charges and point masses.
9. The electron itself, as far as anyone knows, is a point charge / point mass.
10. This is wise policy, as the energy of a point charge, is in fact, infinite.
