Two stones of mass m ₁ and m ₂ (such that . m ₁> m ₂ ) are dropped t time apart from the same height towards the ground. At a later time t the difference in their speed is V and their mutual separation is S . While both stones are in flight

Options

  1. AV decreases with time and S increases with time
  2. BBoth V and S increase with time
  3. CV remains constant with time and S decreases with time
  4. DV remains constant with time and S increases with time

Correct answer

D. V remains constant with time and S increases with time

Step-by-step solution

V = Const & S increases with time
