Question

A 12-V battery maintains an electric potential difference between two parallel metal plates separated by 10 cm. What is the electric field between the plates? a. 1.2 V/m b. 12 V/m c. 120 V/m d. zero

Answer 1

The electric field between the plates is 120 V/m.

(c) is correct option.

Step-by-step explanation:

Given that,

Potential difference = 12 volt

Distance = 10 cm = 0.1 m

We need to calculate the electric field between the plates

Using formula of electric field

`E = (V)/(d)`

Where, V = potential difference

d = distance between the plates

Put the formula

`E =(12)/(0.1)`

`E=120\ V/m`

Hence, The electric field between the plates is 120 V/m.
