I have my assets folder structure like this
assets
javascripts
products
--product.js
--productValidate.js
store
--store.js
I want the project.js and projectValidate.js to be added in my application.js as a part of asset pipe-lining only when actions in product controller is called and store.js when actions in store controller is called. How can i achieve this in rails 3.1?

As Rahul already mentioned, application.js is precompiled and the same for every action. So it does not depend on a particular controller. Application.js should contain the javascript you need for all (or most) of your actions.
However, you may expand your application layout with nested layouts. Let us assume the following structure:
... app/view/layouts/application.html.erb ...
<html>
<head>
<%= javascript_include_tag 'application' %>
<%= yield :javascripts %>
<%= stylesheet_link_tag 'application' %>
<%= yield :stylesheets %>
</head>
<body>
<%= yield %>
</body>
</html>
and a:
... app/view/layouts/products.html.erb ...
<% content_for :stylesheets do %>
<%= stylesheet_include_tag 'products' %>
<% end %>
<% content_for :javascripts do %>
<%= javascript_include_tag 'products' %>
<% end %>
<%= render :template => 'layouts/application' %>
So you just have to add/require your stylesheets and javascripts in the products-files. Notice, all code here should be read as pseudo-code, I did not test it.

As far as I know assets pipilene is something that should be precompiled. So... conceptually it should take all files at once and return just one copiled file, and it is good for caching.
You can store them somewhere out od assets (in puplic, as older Rails do, for example) and include it in depending to current controller and action

I like the approach mentioned in the answer to this question:
Rails 3.1 asset pipeline: how to load controller-specific scripts?
