sir, I have an interesting question of circular motion. if two particles a and b are moving in a circle with angular velocity omega of radius R in an inertial frame. then we have to calculate angular velocity of b with respect to a. this is not my question .my question is that I got two answers for this which are zero and omega .how?

7 years ago by Rithik Chopra

Ans 1 ->

Angular velocity of one object with respect to other can be given by the ratio of relative velocity magnitude of one particle with respect to another in direction normal to the line joining the two particles to the separation between the two... In the case you mentioned you can check it is coming omega and thats the answer not zero...

Does light has mass? if it is there then it must have some momentum....then why momentum of any other body(eg. any vehicle) is greater than the momentum of light since the velocity of light is greater than any moving body

7 years ago by Aman Jain

Ans 1 ->

Light has momentum in its particle nature and these particles we call photons which have rest mass zero... momentum of light is not directly associated only with speed of light... it is given as p = E/c where E is photon energies so it is given as p= h/(lambda)... more details about light momentum and its applications we will study in the topic of special theory of relativity which will be uploaded by end of this year....

can i clear iit chemistry by just solving ncert

8 years ago by gaurav sarmah

Ans 1 ->

Not at all. Maybe mains you can clear but advance is too tricky to go just by relying on ncert and in ncert some concepts are not properly explained. I would suggest 'conceptual inorganic chemistry' by prabhat Kumar RC mukharjee for physical and Rk Gupta for organic. Don't expect too much from rk Gupta because it is not the fault of the book that the subject itself is haphazard. Until you complete whole organic chemistry you will not feel confident about solving any book. In physical if want really tough questions then try ranjeet shahi or n avasthi. Don't worry too much reactions in prabhat Kumar. For inorganic reactions just follow ncert because even if you learn all the reactions given in prabhat Kumar they(iit) can still give reactions for which you will be clueless and it's not worth the time you give just for 1 or Max 2 questions. The amount of reactions are enormous. At least there are 300.

8 years ago by Rohan Jais

Ans 2 ->

Never buy Arihant books for chemistry.For physical chemistry RC Mukherjee for Organic Solomons and Frhyle (ms chauhan edited for jee version)-trust me it is the best book.For inorganic ncert is more than enough.

How EMF is generated by time varying Magnetic Field in a NON-CONDUCTING ring? Is it the actual EMF through which current can be flown?

8 years ago by apoorv agrawal

Ans 1 ->

The magnetic flux through a filamentary loop is changing with time. This flux change induces an emf.emf is induced by a changing magnetic flux. If nothing changes the induced emf is zero.

Ans 2 ->

induced emf is produced in every object which is undergoing change in magnetic flux linked to it. However if the object is non conducting induced current will not flow through the object

a capillary tube is dipped in water vertically. it is sufficiently long so that water rises to max height 10 cm in the tube .The length of the tube inside the water is 25 cms .The lower end of the tube is closed and the tube is taken out and opened again.What length of the water will be remaining in the tube ?

9 years ago by ramesh nagda

Ans 1 ->

50cm as water is held by force of surface tension acting at meniscus and at the bottom... so force becomes twice which can hold double length of column... whereas when tube is dipped... force is only at the meniscus so half length can be held.
