electric force per unit charge experienced by a unit charge at that point
Explanation:
Electric field intensity of a charge at a point is given by the force exerted by that charge on test charge or unit charge at that point
Answer is:
The electric field of any combination of charges is the vector sum of the fields caused by the individual charges.
Explanation:
When several electric fields are working on single charge then the total electric field intensity on that charge is given by the vector sum of all electric field intensities
Answer is:
graphical representation of electric fields.
Explanation:
When a tangent is drawn at any point on electric field line then that tangent gives the direction of electric field at that point so the electric field line represents the elec tric field.
