    @Arshad-ve 7 วันที่ผ่านมา

    This term comes from Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. When an object (like the book) applies a downward force (its weight) on the table, the table exerts an upward force to balance it. This upward force is called the "reaction" because it responds to the force exerted by the object. 2:43 YOU WERE WRONG

    • @SouhardyaSutradhar
      @SouhardyaSutradhar 3 วันที่ผ่านมา

      @Arshad-ve Then what was the purpose of my video. Bro you are absolutely wrong. The reasons are as follows 1. Book doesn’t exert its weight on the surface. Book exerts normal force on the surface which may or maynot be equal to the weight. Weight is the force with which earth pulls an object towards its center and it is a non contact force. Its point of application is at the center of gravity of body and not the contact surface. 2. Now comes your main misconception. You are saying “ Object applies downward force on the table and table exerts a upward force on the object to balance it” How can two forces balance each other if they act on different objects? If i give you a tight slap and you return the slap , will these two slaps balance in each ofher? Two forces can balance each other only if they act on the same object. If i give you two tight slaps , one on your left cheek and one on your right then both will balance each other 😂 3. The upward force is NOT CALLED REACTION because it is a response to the downward force. Both the forces occur at the same instant of time and ANYONE CAN BE CALLED ACTION AND THE OTHER AUTOMATICALLY BECOMES REACTION. THERE IS NO CAUSE-EFFECT relationship between them. Downward force is not the cause of upward force and vice versa. Both of they originate at the same instant of time in pairs. I have already made a detailed video on this topic , do check that out! I hope this helps. If you really are a serious physics learner then you will watch the video below , continue the discussion and accept that you were wrong, otherwise i will just assume that you are a random spammer.

But please remember that according to wave theory light has perpendicular electric and magnetic fields i.e it is an electromagnetic wave. The electromagnetic magnetic wave itself need not be charged but when it interacts with matter , it polarises them or induces a net charge on them.

    @suryavajana9986 หลายเดือนก่อน

    Sir, in this video you explained it with the help of an external resistance. I have thought it in a totally different way in which there is no external resistance. The circuit only consists of conducting wire, the cell and the load. Let there be some finite potential difference across the cell terminals. This also creates a potential difference across the terminals of the load. Here, let's bring the concept of heat generated due to flow of current. For the sake of simplicity, let us assume that across the conducting wire between the positive terminal of the cell and that of the load, there is no heat energy generated (of course there is heat energy generated but relative to the heating of the load, that can be considered negligible). So, the potential energy of the charges (assumed to be some kind of positive charge) remains intact as none of it is getting converted to heat. So the potential energy across the conductor between like terminals of cell and load is 0. Potential difference exists between the unlike terminals of the cell and the load. This is very much sufficient to maintain the current flow. The chemical reaction within the cell does work against the electric force and brings the charges to the higher potential and the cycle continues. So if we consider two points on the conducting wire between the load and the cell, the potential difference between those 2 points is 0, yet current flows across the two points, hence the answer. I had thought of this as a class IX student. I just want to know whether my explanation is correct or not. Please correct me if I am wrong anywhere.

You told that relative to external resistance, resistance of conducting wire is 0. So, nothing opposes the flow of current across 2 given ends of the wire. So, shouldn't infinite current flow when external resistance is very high compared to internal resistance?
