An asteroid orbiting around a planet in circular orbit suddenly explodes into two fragments in mass ratio 1 : 4. If immediately after the explosion, the smaller fragment starts obriting the planet in reverse direction in the same orbit, what will happen with the heavier fragment?
Options:(select one or more)
Answer:
C, D
Solution:
Conserve momentum during the explosion.
If the smaller fragment reverses with orbital speed, the heavier fragment speed rises above escape speed.
After explosion, each fragment moves only under central gravity, so its angular momentum is conserved.
Hence C and D.
