System is at rest for t < 0. Vs = sin 2t. Determine v(t) for t greater than zero.

[A].
[B].
[C].
[D].

Answer: Option D

Explanation:

KCL at node V

Natural response from s + 2, is Ae-2t

For Vs = sin 2t, s = 2j

Steady state response

Since the system is at rest for t < 0

Now substituting t = 0, we get
