Problem

A person in 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 dd 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. [Adv. 2014] #### List - I P. Lift is accelerating vertically up Q. Lift is accelerating vertically down with an acceleration less than the gravitational acceleration #### List - II 1. d=1.2 md = 1.2 \text{ m} 2. d>1.2 md > 1.2 \text{ m} R. Lift is moving vertically up with constant speed S. Lift is falling freely 3. d<1.2 md < 1.2 \text{ m} 4. No water leaks out of the jar Code: a. P-2, Q-3, R-2, S-4 b. P-2, Q-3, R-1, S-4 c. P-1, Q-1, R-1, S-4 d. P-2, Q-3, R-1, S-1
