Please provide explaination and workings. 

The circuit in Figure Q5 is the electrical analog of body functions used in
medical schools to study convulsions. The analog is as follows:
C₁ = Volume of fluid in a drug
C2
R1
R2
νο
= Volume of blood stream in a specified region
= Resistance in the passage of the drug from the input to the blood stream
=
Resistance of the excretion mechanism, such as kidney, etc.
= Initial concentration of the drug dosage
v(t) = Percentage of the drug in the blood stream
(a) Derive the circuit differential equation with v(t) as the variable; (b) Find the initial
values (0+) and dv(0+)/dt; (c) Find v(t) for t> 0 given that C₁ = 0.5µF, C₂ = 5µF,
R₁ = 5 M, R₂ = 2.5 M and the initial value of the voltage across C₁at t = 0¯ is 60 V.
