## Homework Statement

I have attatched both the problems. The figure is essentially the same.

## Homework Equations

1. Energy conservation

2.mgcosx - N = mv^2/r , where N is zero in limiting case.

## The Attempt at a Solution

I solved the whole question and got the answer given in irodov(0.33 gR(7cosx-4))^1/2 .

But answer given in krotov is different.

So, there must be a difference in questions but i am unable to grasp it.

Thanks in advance.
