A) 22V
B) 18V
C) 16V
D) 40V
Correct Answer: A
Solution :
Given \[\text{o }\!\!|\!\!\text{ =4}{{\text{t}}^{2}}+6t+9\]and \[t=2s\] We know that \[\varepsilon =\frac{d\text{o }\!\!|\!\!\text{ }}{dt}\] Here, \[{{\frac{d\text{o }\!\!|\!\!\text{ }}{dt}}_{t\,=2}}=8\times 2+6\] \[\varepsilon =22\,V\]You need to login to perform this action.
