From: JEE Main 2021 (Online) 24th February Morning Shift
Question
A current through a wire depends on time as
i = 0t + t2
where 0 = 20 A/s and = 8 As2. Find the charge crossed through a section of the wire in 15 s.

Correct answer
D11250 C
Step-by-step explanation
Given,
where, 0 = 20 A/s, = 8 A/s2
We know that,
On integrating both sides, we get
q = 11250 C
where, 0 = 20 A/s, = 8 A/s2
We know that,
On integrating both sides, we get
q = 11250 C
