The electric field between two plates is 40 V/m.
To find the electric field between two plates, the values are given are,
distance = 3 cm
Voltage v = 120 v
The electric field between plates is the area where the charges between two plates, influences can be seen. For example, if a charged particle is placed near any charged plate, the plate exerts an electric force to attract or repel the charged particle.
Formula is given as,
E = V / d (v/m)
Substituting the given values,
= 120 /3
=40 v/m
Hence, the answer is 40 v/m.
