Problem

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 of 1.2 m1.2\,\mathrm{m} from the person. In the following, the 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. Column I — P: Lift is accelerating vertically up.; Q: Lift is accelerating vertically down with an acceleration less than the gravitational acceleration.; R: Lift is moving vertically up with constant speed.; S: Lift is falling freely. Column Ii — 1: d=1.2 md=1.2\,\mathrm{m}; 2: d>1.2 md>1.2\,\mathrm{m}; 3: d<1.2 md<1.2\,\mathrm{m}; 4: No water leaks out of the jar
