The Graduate Aptitude Test in Engineering (GATE) is an entrance examination and scholarship test held by the seven Indian Institutes of Technology (IITs) and Indian Institute of Science (IISc) Bangalore. The Ministry of Human Resource Development (MHRD) creates procedures for postgraduate admissions.
The GATE 2015 examination identifies candidates for admission to postgraduate programmes in Engineering (Masters degree programme, both Master of Technology (M.Tech) and Master of Engineering (M.E.), technology, architecture, science and related disciplines at the national level.
The Indian Institutes of Technology (IITs) are considering relaxing the top 20 percentile criterion for eligibility for their engineering entrance exam, JEE Advanced.
The plan was suggested in the meeting of the Joint Admission Board (JAB) of the IITs last week.
Show that the uncertainty relation forces us to reject the semi classical Bohr model for the hydrogen atom
In Bohr atom model we deal with the electron as a classical particle. The allowed orbits are defined by the quantization rules:
The radius r of a circular orbit and the momentum
Here our problem is to prove that the Bohr hydrogen atom approaches classical conditions when n becomes very large and small quantum jumps are involved.
To prove this let us compute the frequency of a photon that is emitted in the transition between the adjacent state
From the left side of the equation is nothing but the curl of the electric field and it tells about the tendency of field lines to circulate around a point . Curl of a vector means how much the vector curls around the point in question. The right side represents the rate of change of magnetic field with time. So from this it could be stated that
Work has different meaning in physics then it has in our everyday life and usage. This article is all about work and what we mean , when use term ‘work’ while studying physics. When we talk about our day to day life a person working on desktop typing is doing very less work in comparison to a person lifting and carrying heavy goods.
A prime number can be divided, without a remainder, only by itself and by 1. For example, 19 can be divided only by 19 and by 1.
Interesting facts about prime
•The only even prime number is 2. All other even numbers can be divided by 2.
•If the sum of a number’s digits is a multiple of 3, that number can be divided by 3.
•No prime number greater than 5 ends in a 5. Any number greater than 5 that ends in a 5 can be divided by 5.
•Zero and 1 are not considered prime numbers.
•Except for 0 and 1, a number is either a prime number or a composite number. A composite number is defined as any number, greater than 1, that is not prime.
