Question on: JAMB Physics - 2001
A student is at a height 4m above the ground during a thunderstorm. Give that the potential difference between the thundercloud and the ground is 107v, the electric field created by the storm is
A
2.0 * 106 NC -1
B
2. 5 * 106 NC -1
C
1.0 * 107 NC -1
D
4.0 * 107 NC -1
Ask EduPadi AI for a detailed answer
Correct Option: B
v = E*d, => E = v/d
i.e E 107/4 = 2.5 * 106 NC-1
i.e E 107/4 = 2.5 * 106 NC-1
