sir when to particle come together there energy is decreased as per Binding energy Zmp+Nmn - M i.e individual particles have greater energy compare when particles come together but here at 20 :57 we say that when two particles come together the rest mass energy is increases this is an contradiction with nuclear physics plz help
Please look at the reply of your question in the last lecture. When certain number of particles come together and bind to each other, the energy has to be released by an amount equal to the binding energy of the system. Or looking another way. If we want to break a bound system, like nucleus, we have to supply energy to the system. Hence the energy of bound system, even at rest, is smaller than the energy when the particles are free and are at rest. Hence the mass of bound system is smaller than the sum of the 'rest' masses of the individual particles. In the present example, the masses in addition to their rest mass energy also had kinetic energy. This kinetic energy is converted into internal energy of the combined mass, which has no kinetic energy, as it is at rest. This additional energy would reflect in an increase of the rest mass energy of the combined mass. Please note that particles like electron and proton can not change their rest mass energy, because they do not have internal structure like a big mass to accommodate internal energy.

shiva1052 thank u sir last lecture mean lec no 16 or lec no 24
shiva1052 thank u so much sir i understood completely now
I meant lecture 15.
I am happy.
I am a jee aspirant . Should I study this for Olympiad ?
Just study for pure fun. JEE/Olympiads do not matter
Thanks, I could understand this problem thanks to you
