Question 19

Essay

In an electrical circuit, a damping force can be provided by a resistor.In this case, the differential equation Ld2Qdt2+RdQdt+1CQ=0L \frac{d^{2} Q}{d t^{2}}+R \frac{d Q}{d t}+\frac{1}{C} Q=0 describes the charge Q on a capacitor in a circuit with inductance L, capacitance C, and resistance R.Suppose L = 1 henry, R = 50 ohms and C = 0.0016 farads.Find a formula for the charge, Q, when Q(0)=0Q(0)=0 and Q(0)=2Q^{\prime}(0)=2 .
