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. P. d=1.2 m
B. Lift is accelerating vertically down with an acceleration less than the gravitational acceleration. Q. d>1.2 m
C. Lift is moving vertically up with constant speed. R. d<1.2 m
D. Lift is falling freely. S. No water leaks out of the jar
  1. a-s;b-r;c-q;d-p;
  2. a-p;b-p;c-p;d-s;
  3. a-p;b-s;c-q;d-r;
  4. a-q;b-p;c-s;d-r;

Solution

In P, Q, R no horizontal velocity is imparted to falling water, so d remains same.
In S, since its free fall, aeff=0
∴ liquid won't fall with respect to lift. !
