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.

1.	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.
Answer» `{:(P,Q,R,S),(2,3,2,4):}` `{:(P,Q,R,S),(2,3,1,4):}` `{:(P,Q,R,S),(1,1,1,4):}` `{:(P,Q,R,S),(2,3,1,1):}` Solution :Speed of efflux can be written as: V 2gh Speed of efflux is HORIZONTAL and REMAINS CONSTANT. Horizontal distance travelled by the water can be written as `d=V sqrt((2h)/(g))= sqrt(gh) sqrt((2H)/(g))= 2 sqrt(h(H))` We can see that above relation is true for all effective values of g with RESPECT to elevator except zero. Because when lift falls freely then effective acceleration due to gravity becomes zero and water doesn.t come out.
