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

Answer:

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

(c) is correct option.

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

$E = \dfrac{V}{d}$

Where, V = potential difference

d = distance between the plates

Put the formula

$E =\dfrac{12}{0.1}$

$E=120\ V/m$

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