Choose the correct answers from the options given.
A:
B:
C:
D:
Correct Answer
B
Explanation
To find the electric field created by the storm at a height of 4 meters above the ground, we can use the formula for the electric field due to a charged object:
Electric field (E) = Voltage (V) / Distance (d)
In this case, the voltage between the thundercloud and the ground is given as 10^7 volts, and the height above the ground is 4 meters. So,
Electric field (E) = 10^7 V / 4 m
E = 2.5 x 10^6 V/m
So, the electric field created by the storm at a height of 4 meters above the ground is 2.5 x 10^6 volts per meter (V/m).
