If I am attracted towards some girl, how can i know whether its love or just inf

On the one hand I think that this is one of those things where only time will tell. A lot of the time people think they're in love, but the novelty wears off. If you end up getting tired of the other person, then you realise in retrospect it was just infatuation. On the other hand, if you have to ASK whether you're in love with somebody, it's pretty safe to say that you're not. You're probably not even infatuated with her. You just find her attractive and would forget about her pretty soon if somebody better came along!
