Study Package for Physics for JEE Main & Advanced

Study Package for Physics for JEE Main and Advanced 2014 is a set of 12 books that are designed to prepare students for the Joint Entrance Examination, carried out by the Indian Institutes of Technology. This package comprises four sections. The Electromagnetism section has four booklets, covering subjects such as magnetic effects of current, electric circuits, direct current and electromagnetic induction. The General Mechanics section has three books, which cover topics such as vectors, circular motion, gravitation and the utilization of Maths in Physics.

Solving physics problems

Lots of time students me how can they solve physics problems and they say that they are having difficulty in solving physics problems. So here I decided to address this issue. Now first of all I would say that do not be afraid of the subject as I say again and again physics to me is most basic of all sciences and you must find the subject interesting and give yourself reasons for studying it for me it was just what I wanted to study till my masters degree and now I like helping students understanding physics.

Brachistochrone Problem

Question
If a particle falls from rest under the influence of gravity from higher to lower point in the minimum time, what is the curve that the particle will follow?
Solution
Suppose v is the speed of the particle along the curve, then in traversing ds portion of the curve time spent would be
