According to the provided information, which of the following options accurately demonstrates the relationship between a force and velocity, confirming that a force that does no work must be velocity dependent?

Options

  1. AdW = 0
  2. BF v = 0
  3. CF is not dependent on velocity
  4. DF must be velocity dependent, with the angle between F and v being 90°. If (v ) changes direction, then F shou

Correct answer

D. F must be velocity dependent, with the angle between F and v being 90°. If (v ) changes direction, then F shou

Step-by-step solution

Correct Option is : (D) F must be velocity dependent, with the angle between F and v being 90°. If (v ) changes direction, then F should also change direction to satisfy the aforementioned condition.
