To get the private key to a known address open the console and enter dumpprivkey <bitcoinaddress>
You need to unlock it first, full list of commands is here:

Finding the public key is a bit complicated, and there is almost no good reason to to so.  Why are you trying to get it?  Is it just simple curiosity?

As shorena has explained, the private key can obtained with the "dumpprivkey" command.

I was trying to play around the multisigs and thus the need for pub key. I guess once I get the priv key, I can find the corresponding pub key via the Elliptic curve property? I am not sure if a single priv key can lead to multiple pub keys(because of the mathematical properties of the curve).

Oh yes..thanks for the responses.

It isn't possible to generate more than one public key for a given private key.  (I'm not certain if it's been proven yet whether it's impossible for two different private keys to generate the same public key).

It looks like there is a program called sx that can be used when working with mult-sig transactions for things like determining the public keys:
