RC response problem

[PG1995]

Hi

I'm trying to solve Practice Problem 7.10. But I'm stuck. I'm not even sure if my procedure is correct. Please help me with it. Many thanks.

Regards

PS: I realize it now. The hard copy of the book I have is 3rd edition while the e-book version is 4th ed. I think there was a mistake in 3rd edition which I was using. So, it's 50V, not 5V.

Hi,

For the circuit shown in problem 7.10 the solution equation is correct, and the voltage at t=0.5 is correct also, and here is a more accurate result:
0.5181916
