Teaching UKPSC Lecturer Mock Test Series 2024 Physics Center of Mass and Linear Momentum Center of Mass
Two bodies P and Q of mass 5 kg and 10 kg respectively are initially at rest. P and Q move towards each other under the mutual force of attraction. At the instant when the speed of P is 10 m/sec and Q is 20 m/sec then determine the speed of the center of mass of the system?
1
5 m/sec in direction of P
2
10 m/sec in direction of P
3
5 m/sec in direction of Q
4
10 m/sec in direction of Q
