Welcome to the Wonderful World of Physics

Dare ask questions! 

“Only those questions are foolish which are not asked”.

While learning Physics ‘questioning every answer is more important than answering every question’.

We created this website where the students can ask even the dumbest doubts without any fear.

There is no one to ridicule them.

We analyze the questions received here and try our level best to answer them satisfactorily with due explanations and illustrations.

Click on the Link Ask A Question to ask your doubts and questions.

It is a good Idea to search whether your question is already answered or not. SEARCH HERE

Magnetic effect(jee)

An electron is shot into one end of a solenoid.as it enters the uniform magnetic field within the solenoid, its speed is 800m\sec and its velocity vector makes an angle of 30° with the central axis of the solenoid. The solenoid carries 4A current and has 8000 turns along its length. Find the revolutions made by the electron within the solenoid by the time it emerges from the solenoid’s opposite end.

Heat & Cold

My brother was arguing that heat & cold could be separate entities and I’ve told him what is known is that cold is the absence of heat and they are just a representation of one thing similarly to how darkness is an absence of light. Having told him that, he asks why are they not considered similar to salt & water? This lead to an interesting thought experiment. At 1st I highlighted the obvious to him of the tangible chemical formation of salt & water making them separate and detectable so, whereas you can’t do the same with heat and cold they aren’t detectable both there. This is when he says that maybe they are. And having recently read about the lucid fallacy, I decide to hear him out, casting aside common examples that show they are a mere representation of low and high temperature.  He basically said if they aren’t separate entities wouldn’t a vacuum have no temperature rather than be cold?
