A person in a lift is holding a water jar, which has a small hole at the lower end of its side. When the lift is at rest, the water jet coming out of the hole hits the floor of the lift at a distance d of 1.2 m from the person. In the following, state of the lift's motion is given in List I and the distance where the water jet hits the floor of the lift is given in List II. Match the statements from List I with those in List II and select the correct answer using the code given below the lists.
| List I | List II | ||
| A. | Lift is accelerating vertically up. | ||
| B. | Lift is accelerating vertically down with an acceleration less than the gravitational acceleration. | ||
| C. | Lift is moving vertically up with constant speed. | ||
| D. | Lift is falling freely. | No water leaks out of the jar |
Options
- Aa-s;b-r;c-q;d-p;
- Ba-p;b-p;c-p;d-s;
- Ca-p;b-s;c-q;d-r;
- Da-q;b-p;c-s;d-r;
Correct answer
B. a-p;b-p;c-p;d-s;
Step-by-step solution
In P, Q, R no horizontal velocity is imparted to falling water, so d remains same.
In S, since its free fall,
liquid won't fall with respect to lift.
In S, since its free fall,
liquid won't fall with respect to lift.
