Practise IB Physics SL D.2.6 by defining, calculating and interpreting electric field strength around charges and plates.
Define electric field strength.
force per unit charge; on a positive test charge / on a positive small charge;
The diagram shows a pair of horizontal metal plates. Electrons can be deflected vertically using an electric field between the plates.

Calculate the force on an electron between the plates when the electric field strength has a value of 2.5×103NC−1.
F=2.5×103×1.6×10−19;
4.0×10−16 N;
