Two particles of masses 2 kg and 3 kg are at rest and are separated by 10 m. If they move towards each other under the mutual force of attraction, they would meet at :
Answer & explanation
Correct answer: option 3
The two bodies would meet at their centre of mass.
Sum of masses = 2 + 3 = 5 kg
Let us consider the 2 kg body as a reference ;
The centre of mass from the 2 kg body =(3 x 10) / 5
= 6 m.
