Answer:
430.
Explanation:
If we know that 0.5 is half of a whole number, then we can simply understand that we need to 215 x 2 to get our answer.
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

Where, V = potential difference
d = distance between the plates
Put the formula


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