Positive point charge (Add image)
Negative point charge (Add image)
Between two unlike point charges (Add image)
Between two positive point positive charges (Add image)

Between parallel plates (Add image)
Electric field strength
Depends on:
Potential difference across the plates
E ∝ V
Distance separating the plates
E ∝ 1/d
E = V/d
Uniform electric field
Represented by equally spaced, parallel lines
An electric field of the same magnitude and direction at all points in the central region of the parallel plates
Units
SI unit: N.C-1
Alternative unit: V.m-1
Force on a charged particle in a uniform electric field
E = F/q
and
E = V/d
F/q = V/d
F = (Vq)/d
Deflection of charged particles in a uniform electric field
