The formula for calculating the magnitude of electric field at point P is E = kQ/r^2, where k is the Coulomb's constant, Q is the charge of the source, and r is the distance between the source and point P.
The magnitude of electric field at point P is inversely proportional to the square of the distance between the source and point P. This means that as the distance increases, the electric field strength decreases.
The magnitude of electric field at point P is affected by the charge of the source, the distance between the source and point P, and the medium through which the electric field is passing. Additionally, the direction of the electric field lines also influences the magnitude at point P.
No, the shape of the source does not affect the magnitude of electric field at point P. As long as the distance and charge remain the same, the magnitude of electric field at point P will be the same regardless of the source's shape.
The magnitude of electric field at point P can be represented graphically by using electric field lines. These lines point in the direction of the electric field and are closer together where the electric field is stronger and farther apart where the electric field is weaker.
