The screening was carried out through a carefully designed video quiz. The videos and questions used for screening
test are given below:
No
Question(s)
Video Link
1
The video contains sound of four different frequencies viz. (i) 300 Hz (ii) 600 Hz (iii) 1000 Hz and (iv) 1500 Hz. The students
were expected to identify these frequencies by listening to the sound.
2
There are two questions based on this video,
In the beginning, water mass was rotating. Give a possible reason for it.
In the central region of the bottom of the vessel there are no points of steam formation. Guess a reason for it.
3
When water was poured on the hot plate it was distributed in separate drops. Why the drops dance on the hot plate so fast as if there is no friction between them?
4
Why is it easier to take off the kurta in latter part of the video than in the former part?
5
Find time period of the pendulum shown in the Video.
6
Mark the correct options (More than one options may be correct):
Question (1)
F1=W, F2 is greater than W
F1=W, F2=W
F1=W, F2 is less than W
F1 is not equal to W, F2 is not equal to W
Question (2): All torques are about the diameter of the pipe in hand.
Torque of F1 is T1 and Torque of F2 is T2. Torque of W in case 1 is T3 and torque of W in case 2 is T4.
T1=T3 and T2=T4
T2 is greater than T1
T2=T1
T2 is less than T1.
7
(More than one options may be correct) The stream from the lower pipe covers the least distance. This is because,
Pressure of water in the bottle at the lower pipe is least.
Pipe diameter of the lower pipe is smaller than the others.
Height of the lower pipe over the floor is smaller than for other pipes.
Pressure of water in the bottle at the lower pipe is largest.
8
(More than one option may be correct)
The upper flat face of the magnet is north pole. Consider the magnetic field due to this magnet at the tip of the loop. Its direction is close to
Vertically upwards
Vertically downwards
Horizontal, towards or away from the battery
Horizontal, towards or away from the experimenter.
9
There are three questions based on this video,
The balance shown in video measure mass in grams. Calculate the tension in the string when the hanging mass is stationary and rotating mass (eraser) rotates at constant speed?
The hanging mass starts rising up when the eraser is rotated faster. Explain?
When hanging mass is pulled down by hand, the eraser starts rotating faster. Why?
10
The cylinders and inclined plane are made up of non-magnetic material. The surface properties of the two cylinders are also same. The questions based on this video are,
The time taken by the two cylinders to reach the ground changes with change in inclination angle. The time taken is more for larger inclination angle or smaller inclination angle? Why?
The Yellow Color Cylinder takes lesser time in comparison to Blue Color Cylinder. Explain in detail?
11
In first case (when the book and the paper are dropped separately from the same height) the book reaches the ground earlier than the paper. In second case (when paper is placed over the book) they reach the ground together. Why?
12
The flexible corrugated pipe is hollow and open at both ends. When the pipe is rotated, the bits of paper are being sucked by the pipe at one end and thrown out from the other end. Why?
When the corrugated pipe is rotated faster, it produces a roaring sound. Explain the physics behind this sound?
13
The oscillations of the pendulum stops very fast when Aluminium sheet is placed below the oscillating magnet. Why?
14
The students were given a six inches plastic scale.
What is the least count of the plastic scale given to you?
Measure the length and breadth of this paper? Calculate the area of the sheet and the percentage error in the area?
15
Why the water is not coming out of the hole when the cap is closed? What will happen if we increase the hole size?
Why the water starts coming out when the cap is removed?
16
It is not possible to drink water with punctured straw. Why?
17
The bulb shown in the video is a normal household bulb of 100 Watt power rating.
Calculate the resistance of the bulb filament?
How much is the difference between calculated value and measurement shown by the multi-meter? Why these two values are different?
18
Which bottle was emptied first? Give explanation?
