Both electric and magnetic fields are produced by the electromagnetic force, when we combine these both fields electromagnetism is produced.
Explanation:
Electric field and magnetic field are different but there is a connection with these both fields that is an electromagnetic force. Moving electric charge produces a 'magnetic field' and induced magnetic field leads to an electric field. Magnetic and electric fields are perpendicular to each other. Combining electric field and magnetic field electromagnetism is created. Two kinds of charge are associated in the electric field and in the magnetic field, two magnetic poles are associated.
The potential difference between the plates is 8 V.
Explanation:
Given that,
Area of plates = 0.40 m²
Charge
Distance = 4.0 cm
We need to calculate the electric field
Using for formula of electric field
Where, q = charge
A = area
Put the value into the formula
We need to calculate the potential difference between the plates
Using formula of potential difference
Where, E = electric field
d = distance
Put the value into the formula
Hence, The potential difference between the plates is 8 V.
