Matching Sports Equipment to Sports
This question requires matching specific pieces of sports equipment from List-I with the sports they are used in, listed in List-II. Let's break down each item:
Understanding the Equipment and Sports
- (A) Antennae: These are flexible rods placed vertically at the edges of the net in Volleyball to help officials determine if the ball is in play or out of bounds when it crosses the net.
- (B) Alternating possession arrow: This marker is used in Basketball to indicate which team has the next possession after a jump ball. The arrow flips after each subsequent jump ball situation to ensure fair possession changes.
- (C) Goalposts: These are the upright posts and the crossbar that define the goal area in sports like Football (soccer), American football, and rugby. In the context of the given options, it refers to Football.
- (D) Bails: These are the small, wooden pieces placed on top of the three stumps that form a wicket in Cricket. When the bowler hits the stumps with the ball, the bails are dislodged, signifying that the batsman is out.
Summary of Matches
Based on the above explanations, we can establish the correct pairings:
| List-I (Equipment) | List-II (Sports) |
| (A) Antennae | (III) Volleyball |
| (B) Alternating possession arrow | (I) Basketball |
| (C) Goalposts | (IV) Football |
| (D) Bails | (II) Cricket |
Identifying the Correct Option
Comparing our derived matches with the given options, the correct combination is (A) - (III), (B) - (I), (C) - (IV), and (D) - (II). This corresponds to option 3.

A stone is thrown horizontally from the top of a 20 m high building with a speed of 12 m/s. It hits the ground at a distance R from the building. Taking g = 10 m/s2 and neglecting air resistance will give :
A sphere of volume V is made of a material with lower density than water. While on Earth, it floats on water with its volume f1V (f1 < 1) submerged. On the other hand, on a spaceship accelerating with acceleration a < g (g is the acceleration due to gravity on Earth) in outer space, its submerged volume in water is f2V. Then:
A railway wagon (open at the top) of mass M1 is moving with speed v1 along a straight track. As a result of rain, after some time it gets partially filled with water so that the mass of the wagon becomes M2 and speed becomes v2. Taking the rain to be falling vertically and the water stationery inside the wagon, the relation between the two speeds v1 and v2 is :
Consider the following statements:
1. Distance between the longitudes becomes zero on North Pole and South Pole.
2. Distance between the longitudes is maximum on the Equator.
3. Number of longitudes is more than number of latitudes.
Which of the statements given above is/are correct?
One block of 2⋅0 kg mass is placed on top of another block of 3⋅0 kg mass. The coefficient of static friction between the two blocks is 0⋅2. The bottom block is pulled with a horizontal force F such that both the blocks move together without slipping. Taking acceleration due to gravity as 10 m/s2, the maximum value of the frictional force is :
