30-((l*c)*d^2vc/dt^2)-((l/r)dvc/dt)-vc=0

where,

l=29.5*10^(-3)

c=20*10^(-6)

r=10

here vc=voltage across capacitor and all initial conditions are zero

Is there a relationship between vc and c or is vc a different variable?

vc is a different variable. here vc means voltage across capacitor

If the equation is 30-l*c*(diff(vc(t), t, t))-l*(diff(vc(t), t))/r-vc(t) = 0 then it cannot be solved without two additional boundary conditions.

can you please show the steps involved

I used dsolve() from the symbolic toolbox.
