The Attempt at a Solution
I think the circuit given above is incorrect due to the presence of the two resistors . I have never seen/done a problem where equivalent capacitance is to be calculated across two points in a circuit , having resistors along with capacitors .
Is it that there is a prining mistake such that the top two resistors are actually capacitors ? If that is the case then net capacitance can be calculated .
I might be wrong .
