Electric Fields and Electric Forces

If q0 is +ve Force Fo experienced by charge is in the same direction as the electric field. If qo is -ve Force Fo experienced by charge is in the opposite direction as the electric field.

Electric Field Points towards -ve charge. Electric Field points away from +ve charge.

Principle of Superposition of Electric Fields: The total electric field at point P is the vector sum of the fields at P due to each point charge in the charge distribution.

The magnitude of the electric force that two point charges exert on each other is (a) proportional to the product of the magnitudes of their charges and (b) inversely proportional to the square of the distance between them.

The electric force on a charged object is exerted by the electric field created by other charged objects.

Coulombs Law

The magnitude of the electric force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Electric Charge and Charging by Induction

Charging a metal by induction:

Mass of electron = 9.109x 10^-31 kg

Mass of proton = 1.67x10-27 kg

Charge of proton and electron: 1.602 × 10^-19 C

mass of neutron: 1.67x10-^27 kg
