Variable Mass system is a important concept of Center of Mass chapter for IIT JEE exams. In variable mass the system mass keeps on changing with time due to which it experiences a thrust force. Here Mohir Sir answers following
What is Rocket Propulsion equations ?
How to derive rocket propulsion equation in Variable mass ?
What is thrust force acting on floor when a chain free falls on it ?
What is thrust force experienced by a vessel or Pipe when water ejects from it ?
Question in JEE Main on variable mass concepts ?
