## Homework Statement

A lightning bolt carrying 30,000 A lasts for 50 microseconds. If the lightning strikes an airplane flying at 20,000 ft, what is the charge deposited on the plane?

## Homework Equations

q(t) = [tex]\int[/tex] i(x)dx

## The Attempt at a Solution

So, using the equation above I found the charge of the lightning bolt to be 30,000A * 50 x 10^-6

q(t) = 1.5 c

Then to find charge of the airplane

q(t) = [tex]\int[/tex] 20,000dx from 0 to 50 microseconds

q(t) = 20,000x

q(t) = 20,000 (50 x 10^-6) = 1

I'm a bit rusty on my physics as you can see. Maybe someone can direct me to a more precise approach. Thank you
