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 options given below the lists.
| List - I | List - II |
|---|---|
| P. Lift is accelerating vertically up. | 1. d=1.2 m |
| Q. Lift is accelerating vertically down with an acceleration less than the gravitational acceleration. |
2. d > 1.02 m |
| R. Lift is moving vertically up with constant speed. |
3. d < 1.2 m |
| S. Lift is falling freely. | 4. No water leaks out of the jar |
If $$\lambda$$Cu is the wavelength of K$$\alpha$$ X-ray line of copper (atomic number 29) and $$\lambda$$Mo is the wavelength of the K$$\alpha$$ X-ray line of molybdenum (atomic number 42), then the ratio $$\lambda$$Cu/$$\lambda$$Mo is close to
