    2. Sir, in first question, in the FBD of block of mass M1 you drew the components of N3 (N3costheta and N3sintheta) as well the whole N3 itself and same in M2 (the rod). Is it compulsory to draw all three of them together or we can draw only the components of the force N3? This is because if I add N3costheta and N3sintheta I will get twice of N3. Kindly answer sir.

    3. Sir, you said that tension always acts away from point of contact of string, then the tension developed in the string due to the force applied by the boy should be away from the direction of applied force. Why do you think the tension in the string is along the direction of applied force?

    4. sir please help me, currently I am completely dependent on your lectures for physics as I am preparing for IIT JEE but i also want to read a textbook which book should I prefer between NCERT or HC VERMA for reading purpose.
    4 years ago by Rohan yadav
    Ans 1 ->
    Both the books are a must,Ncert builds your basic level(for which sir's lectures are also sufficient)then the theory pirtion can be read from hc verma which is concise and straightforward.For problem practice do the questions of Hc verma ,ncert ,sir's books and the solved examples and mcq tests on website.Hope it helps!

    if youre studying for jee main, then sir lectures plus ncert plus hc verma and dc pandey is enough but if you want t clear advanced then you are wasting time now , you should go to coaching as there its actually harder in fact of a new level . solve the previous year papres

    9. Sir, how do we come to know which component to mark as N3sin() and N3cos(). Do we always mark horizontal component as N3sin()????

    11. sir why normal force and weight are not considered to be action-reaction pair?
    8 years ago by R Rohit
    Ans 1 ->
    action reaction force always act on different bodies but here we talking about single body and all the forces that acting on it only
    8 years ago by Harpreet Kaur
    Ans 2 ->
    AND ONE MORE REASON FOR ACTION- REACTION PAIR FORCES MUST BE OF SAME KIND. MG AND N ARE TWO DIFFERENT TYPES OF FORCES ONE IS GRAVITAIONAL FORCE AND OTHER IS CONTACT FORCE.
