In the 3rd problem, I am confused about the integration part. I am getting a factor of 2 after integration for phi. But in the answer it is not present.

thanks mam.. this was actually where I was stuck
• Abhishek singh
here is the solution. this is called gradient theorem
Deepanshu Chaudhary
yeah thanks.. this part is clear but im still not getting how is it x^2y+ xz^3
• Ruby negi
hope now it is clear .
Deepanshu Chaudhary
But if we integrate x^2 wrt y then we don't get the same answer. Nor do we get the same after integrating wrt z
• Deepanshu Chaudhary
but my doubt is why can't we do it Directly??
• Deepanshu Chaudhary
Actually this should be the solution
• Abhishek singh
Rubii has attached a solution. And it is right, but there is a little correction. Phi is just phi, it has no components (you are absolutely right) . you can calculate phi from all ...

But look at the answer below the question. It is 202 not 404. That is the 2 ka factor I have mentioned in my question
• Ruby negi
solution....
