Expert Solution
Step 1

(Note: I think there is a typing error in the question and it should be ω = 2π.Then the circuit remains of type AC, also voltage division for capacitance is usually for AC circuits. But I will solve the question according to the given data)

Given

ωt = 2πTherefore the voltage source becomes V = 5* cos(ωt) = 5*1 = 5VTherefore it has a constant 5V supply just like DC source and therefore be considered as DC souce of 5V

Let

C1 = 100pFC2 = 25pFC3 = 40pFC4 = 80pF
