Q. If
→vwm is the velocity of a man relative to water,
→vw is the velocity of water, and
→vm is the velocity of man relative to ground, match the following:
| Column I |
| Column II |
I. | Minimum distance for vmw>vw | a. | θ=sin−1(vmwvw) |
II. | Minimum time for vmw≥vw | b. | →vm⊥→vw |
III. | Minimum distance for vmw<vw | c. | →vmw⊥→vw |
iv. | Minimum time for vmw<vw | d. | θ=sin−1vwvmw |
where
θ is the angle between
→vmw and the width of the river.
