AC EMF Across R-C Circuit

An ac source of 50 V (r.m.s value) is connected across a series R - C circuit. If the r.m.s voltage across the resistor is 40 V, then the r.m.s voltage across the capacitor is

If the potential difference across the inductor (3mH) is same as that across the condenser (30muF) in a series R-L-C circuit, then the frequency of the applied e.m.f. is

If the P.D. across the inductor (3mH) is the same as that across the condenser (30 mu F) in a series R-L-C circuit, then the frequency of the applied e.m.f. is
