Two particles A and B initially at rest, move towards each other by mutual force of attraction . At the instant when the speed of A is n and the speed of B is 3 n, the speed of the centre of mass of the system is move towards each other by mutual force of attraction . At the instant when the speed of A is n and the speed of B is 3 n the speed of the centre of mass of the system is Two particles A and B initially at rest September 20, 2020 Category: Uncategorised (JEE Advanced Physics by BM Sharma + GMP Solutions) , Facebook Messenger WhatsApp Share this:TwitterFacebook Related
