A balloon of mass M is descending at a constant acceleration α. When a mass m is released from the balloon it starts rising with the same acceleration ‘α’. Assuming that its volume does not change, what is the value of m?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
When balloon is descending, Mg – F b = Mα
⇒ F b = Mg – Mα ...….(1)
When balloon is ascending, F b – (M – m) g
= (M – m)α …… (2)
from these two equations, m =
