Sorry

i have one question to ask

how to check the v.dl part in this problem

i cannot do this problem as it is too hard to integrate the equation

How did griffith get this long-horrible equation(see the orange circle)?

it sounds unreasonable and too hard to get

and is it possible that there are

other faster ways to check the v.dl part in this problem?

thank you
