A lightning bolt carrying 15000 A lasts for 50 $\mu s.$ If the lightning strikes a tractor and the tires are assumed to be perfect insulators, the charge deposited on the tractor is 0.75 $C$.

If the a lightning bolt carrying 17500 A lasts for 100 $\mu s,$ determine the charge deposited on the tractor if the tires are assumed to be perfect insulators.

$Q =$ $C$
