homework question? This site isn't for answering specific problem sheet type q's. – Nic Sep 26 '11 at 15:50
Welcome to Physics.SE! These appear to be questions copied directly from a set of exercises and as such are off-topic (see the FAQ). You are welcome to ask about the underlying concepts provided that these questions would not be duplicates. To approach this problem you should ask yourself two question: 1) what generates electromagnetic radiation in the first place and 2) how would moving the plates of the capacitor affect the capacitance and thus the behavior of the circuit. – dmckee Sep 26 '11 at 15:52
