Two parallel plates are 2.0 cm apart and have a potential difference of 400 V across them. What is the electric field strength between the plates? A force of 1.2 x 10-12 N south acts on a charge at point P in an electric field of strength 3.6 x 10 NC' south. Calculate the magnitude and sign of the charge. The electric field between two parallel plates is 5 x 10' V m. If they are 7.5 cm apart, what is the voltage across them The potential difference across two parallel plates is 300 V. This produces an electric field of strength 1.5 x 10*Vm What-is the separation between the plates?
