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 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 list. 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>1.2 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 List IList IIP. Lift is accelerating vertically up 1. d=1.2 m Q. Lift is accelerating vertically down with an acceleration less than the gravitational acceleration2. d>1.2 m R. Lift is moving vertically up with constant speed3. d<1.2 m S. Lift is falling freely 4. No water leaks out of the jar
