samigupta8 · Answer

I got radius of curvature of interface to be infinity

parthkohli · Answer

Yeah, hmm. 
And what does that imply?

samigupta8 · Answer

Flat surface between the two

parthkohli · Answer

Indeed...

So how to continue with this? I am unable to get through it.

parthkohli · Answer

Wouldn't that mean zero distance? I don't understand liquids that well.

samigupta8 · Answer

0 distance? On what basis you ended up with this result?
