My article is approved but cash and point is not given only in that section is 0

This happens in many cases. An article may be awarded any points and cash based on merit. Approval does not mean that some cash or points must be given.

There are many articles which are approved but not credited. It solely depends on quality of article and cash is credited accordingly.

Chandan, for your information, mobile reviews do not get any Cash Credits but only points are awarded. Again the points depend upon the quality of the article and if there are multiple reviews for one particular model, then may not get points either.
