An electric field is a force field that surrounds electrically charged particles and influences the movement and behavior of other charged particles within its vicinity.
The electric field strength between 3 charges is calculated using the formula E = kQ/r^2, where k is the Coulomb constant, Q is the magnitude of the charges, and r is the distance between the charges.
Yes, the direction of the electric field can change depending on the positions and magnitudes of the 3 charges. The electric field always points in the direction of the force that a positive test charge would experience if placed in the field.
The electric field strength is inversely proportional to the square of the distance between the charges. This means that as the distance between the charges increases, the electric field strength decreases.
The direction of the electric field indicates the direction in which a positive test charge would move if placed in the field. This information is important in understanding the behavior and interactions of charged particles in the presence of multiple charges.
