Answers (1)

\mathrm{ I=2 t+3 t^2 }

\mathrm{ I=\frac{d q}{d t} \Rightarrow d q=I d t=\left(2 t+3 t^2\right) d t }

\mathrm{ q=\int d q=\int_2^3\left(2 t+3 t^2\right) d t }

\mathrm{ =\left[t^2+t^3\right]_2^3=(9+27)-(4+s) }

                         \mathrm{ =36-12 }

                         \mathrm{ =24 c }

Hence option 2 is correct.
