A) 60 C
B) 24 C
C) 48 C
D) 30 C
Correct Answer: C
Solution :
Let dq be the charge which has passed in a small interval of time dt, then \[dq=1dt=(4+2t)\,dt.\] Hence, total charge passed between interval \[t=2s\] and \[t=6s\] \[q=\int_{2}^{6}{(4+2t)\,dt=48C}\]You need to login to perform this action.
