Final answer:
The expression for the magnitude of the electric field in the vicinity of the small charge due to the charge distribution on the conductive plate is given by VAB E = d.
Step-by-step explanation:
The expression for the magnitude of the electric field in the vicinity of the small charge due to the charge distribution on the conductive plate can be obtained using the equation VAB E = d. This equation relates the electric field strength (E) to the voltage (V) between the plates and the plate separation (d).So, the magnitude of the electric field is directly proportional to the voltage between the plates and inversely proportional to the plate separation.For example, if the voltage between the plates doubles, the magnitude of the electric field also doubles, assuming the plate separation remains the same.
