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

Question

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
