Dear Aspirant,

the repeated questions for NEET examinations are generally in most cases low, as the level of competition is very high. In most cases similar kinds of questions are asked instead of repeating the same question. However, there are a few times where a question or two are repeated from the previous years. Hence to get to know of some of these repeated questions or similar questions that are asked through out the year in NEET, you may solve the previous years question papers. They are very beneficial as it not only gives you an idea of the similar questions but also helps you get familiar with question paper pattern.

Hello Candidate,

The galvanometer is a simple electrochemical device which is used to measure the supply of current in the circuit or in a loop.

Galvanometer consists of several divisions including main scale divisions and small scale division for accurate measurement of the current supply, when the fluctuations age produced in the device upon changing the voltage and other electrical parameters.

Hope this information helps you!!

Dear student,

I would not recommend you to study the theory of modern physics from H.C Verma. The theory given in the book is not sufficient and does not explains the concept well. However the problems are really good. I would advice you to study this topic from Resnick Halliday, it is a great book for theory for physics. You concepts will build up strongly and you will understand the topic really well. After reading from this book you can go to hc verma and solve it's problems.

Hello Candidate,

Simple Harmonic Motion is one of the easiest chapters in 11th Physics. If you are preparing for the NEET Exam, then surely you have to read this chapter. Now before studying this chapter, there is not any fix thing, that you have to study some chapters before reading it.

But I am listing some chapters, that you can study before starting the SHM chapter. These are listed orderwise below.

1. Kinematics
2. Newton Laws of Motion
3. Work, Energy and Power
4. Rigid Body Dynamics
5. SHM

Hope it helps.

Hi candidate,

You can start the surface tension chapter by gradually learning from the basics such as force due to surface tension, pressure in a bubble due to surface tension below and above water and the role of surface tension in day to day life activities.

Since in the class 11th examinations the questions are mostly focused on derivations and a bit of numericals, hence the NCERT books can definitely help you to get a good score in the exams.

Hope that this answer helps you

Hello

The order of reactivity of halides with amines are is RI>RBr>RCl.

Lets us take a example:

When Excess ethyl iodide is treated with ammonia then the product formed is tetraethylammonium iodide

NH3+C2H5I-------->C8H20N+

Tetra ammonium iodide is a quaternary salt .

Good Luck
