Oct 02, 2020 · Let us consider a positive charge q 0 which is allowed to move in an electric field produced between two oppositely charged parallel plates as shown in the figure. The positive charge will move from plate B to A and will gain K.E.If it is to be moved from A to B,an external force is needed to make the charge move against the electric field and will gain P.E.Let us impose a condition that as the charge is moved from A to B, it is moved to keep electrostatic equilibrium,i.e.,it moves with ... Consider two parallel sheets of charge A and B with surface density of σ and -σ respectively .The magnitude of intensity of electric field on either side, near a plane sheet of charge having surface charge density σ is given by. E=σ/2ε 0. And it is directed normally away from the sheet of positive charge.
Since the field lines are parallel and the electric field is uniform between two parallel plates, a test charge would experience the same force of attraction or repulsion no matter where it is located in the field. That force is calculated with the equation F = qE where both F and E are vector quantities and q is a scalar quantity.
