A force F acting on a body depends on its displacement S as F S^ -1 / 3 . The power delivered by F will depend on displacement as

Options

  1. AS^ 2 / 3
  2. BS^ -5 / 3
  3. CS^ 1 / 2
  4. DS^0

Correct answer

D. S^0

Step-by-step solution

F S^ -1 / 3 or a S^ -1 / 3 or V d S^ -1 / 3 d s (a=V d V d s ) Integrating we have, V^2 S^ 2 / 3 or V S^ 1 / 3 Now, power P F V S^ -1 / 3 S^ 1 / 3 or P S^0
