IIT-JEE Physics previous questions based on Bernoulli's... Continuing with our discussion on Bernoulli's theorem, we take a look at some of the previous questions asked in the Physics paper of IIT-JEE dealing with the same.We would also be trying to find a pattern in the theoretical aspects of the said questions. [ Answers in the next post dealing with Bernoulli's theorem ] *1]...

Question of the Week : Answer to IIT-JEE Physics 2009/Optics Given below is the answer to Optics question from IIT-JEE Physics paper 2009 V is taken by calculating the root of  2 x 10 x [ 20 - 12.8 ] which gives  12 m/s.... now, Considering  the diffraction at the water surface, v/u2  = u/u1  or  dv/dt  = u2/u1 x dv/dt     i.e,  dv/dt  = 4/3 x 12 = 16 m/s. Hence,option...

Question of the Week : from IIT-JEE 2009/Physics /... A ball is dropped from a height of 20 m above the surface of water in a lake. The refractive index of water is 4/3. A fish inside the lake, in the line of fall of the ball, is looking at the ball. At an instant when the ball is 12.8 m above the water surface, the fish sees the speed of the ball as (Take g = 10 ms–2) (a)...

Question of the Week : IIT-JEE Physics 2009 /Mechanics

Category : CBSE +2 Physics, IIT-JEE Physics, NCERT Physics

 

If the resultant of all the external forces acting on a system of particles is zero, then from an inertial frame,one can surely say that

A] linear momentum of the system does not change in time

B] kinetic energy of the system does not change in time

C] angular momentum of the system does not change in time

D] potential energy of the system does not change in time.
 
Ans : ΣF =0P=constant       hence option A] is correct.

Learning Physics is often considered a tough nut to crack,especially as it involves two basic steps..that is understanding a theoritical concept,and then applying it in the problem / workout at hand.The issue here is,not only in understanding the concept,but the factual application of the principle involved in the a] right manner b] right level and the c] right context.Hence,even for a studious person,one or all of the above  factors is bound to go wrong.

Welcome to PHYSICSMYND, the web resource which will enable you to tackle all the physics learning related issues you will probably encounter .Eventhough the content level would be mainly aimed at IIT-JEE PHYSICS EXAM done in India, it would be equally suitable for a student following any University level Physics classes including the International Cambridge Examinations.

Last,but not least this site would also have  info feeds on path breaking Science & Technology Applications with special emphasis on the physics of  those applications.
