NEWTON'S LAWS OF MOTION & Friction JEE Chapterwise Analysis, Weightage and Overview

Do not get disillusioned with the 4 questions asked over the years. This is one of the most important sections and should be treated likewise. Free Body Diagrams are introduced at this stage which are among the fundamentals that support a lot of Physics Problems. Momentum and Impulse problems are common. .

Q.

Two blocks of mass  are placed in contact with each other on an inclined plane as shown in figure. The co-efficient of friction between  and surface is  and between  and surface is .

                                                                 

 

Column I

 

Column II

 (A)

  

 (p)

Q.

Two blocks of same mass m = 10 kg are placed on rough horizontal surface as shown in figure. Initially tension in the massless string is zero and string is horizontal. A horizontal force  is applied as shown on the block A for a time interval t = 0 to t = 6 sec.

Here F is in Newton and t in second. Friction coefficient between block A and ground is 0.20 and between block B and ground is 0.30.  Match the statements in Column-1 with the time intervals (in seconds) in Column-2.
