in this particular problem, it has been given that a large lightning bolt haven't got int. I just didn't do it as I is equal to 20,000 amperes and it moved a charge off 30 columns. So Delta Q is equal to Turkey grooms, and we need to find its duration. So basically, we need to find their thirties equal to homage. To solve this problem, we need to use the formula as Isaac Walton Delta Q order titty and here in this case, we need to find the time duration. So Delta T is equal to charge with respect. I got it now putting the values. They're like us 30 grams and while you have current as 20,000 and peaceful mentioned it us to engage in good generous to three amperes, which is coming as 1.5 into terrorists to minus three seconds. So which is known as 1.5 milliseconds. This will be our answer, which denotes the duration off. 1.5 milliseconds will be required
