The force felt by a unit positive charge or test charge when it's kept near a charge is called Electric Field. The electric field is also defined as the region which attracts or repels a charge. The electric field is a vector quantity and it denoted by E.

1. Electric Field

2. Electric Field
 Electric force between a charge and unit positive
charge is called electric field
 The S.I unit of electric field is Newton/Coulomb
 Electric field is a vector quantity
 It is also called force per unit charge
 It is represented as E = kq/ r2 𝐫

3. Direction of Electric Field
 If the charge is positive, then direction of electric
field is radially outward
 If the charge is negative, then direction of electric
field is radially inward

4. Electric Force
 It is denoted by F and is represented as F = q E
 Electric Force is a vector quantity
 Direction of Electric force is away in case of
positive charge and towards in case of negative
charge

5. Electric Field due to Multiple Charges
 Electric Field can be added using principle of
superposition, if there are more than two charges
producing electric fields
 The net electric field is represented as
 E = E1+ E2 + E3 + …………+ En

6. Physical Significance of Electric Field
 Electric field explains the electronic environment
of system of charges
 Electric field is used widely in electrodynamics to
study about motion of a charge
 Field is defined as something which is defined at
any point and varies accordingly
