A) \[bx\]
B) \[x/a\]
C) \[x/b\]
D) \[x/ab\]
Correct Answer: C
Solution :
\[a+b{{v}^{2}}={{x}^{2}}\] Þ \[0+b\left( 2v.\,\frac{dv}{dt} \right)=2x\,.\,\frac{dx}{dt}\] Þ \[v.b\frac{dv}{dt}=x\,.\,\frac{dx}{dt}\] Þ \[\frac{dv}{dt}=\frac{x}{b}\] , \[\left( \because \frac{dx}{dt}=v \right)\].You need to login to perform this action.
