Question

Set up a dropper with ink in it vertical at a height say 20 cm above a horizontally
placed sheet of plain paper. Release one ink drop; observe the pattern, if any, on the
paper. Vary the vertical distance and repeat. Do this exercise a total of four times.
Observe, and write about the relationship between the pattern formed versus the
vertical height

Answer 1

Answer:

There will be one paper of two and a half hours

duration carrying 80 marks and Internal Assessment

of 20 marks.

The paper will be divided into two sections, Section I

(40 marks), Section II (40 marks).

Section I: Will consist of compulsory short answer

questions.

Section II: Candidates will be required to answer

four out of seven questions.

Step-by-step explanation:

Answer 2

The size of the pattern of the ink drop increases, when the vertical distance increases.

• A dropper with ink in it is placed vertical at a height of 20 cm above a horizontally
• placed sheet of plain paper.
• A drop of ink is released and the pattern is noted.
• Now, the dropper with ink in it is placed vertical at a height of 30 cm above the sheet and the ink is droped.
• The size of the pattern formed by the ink drop is slightly higher than the first one.
• Then, the dropper with ink in it is placed vertical at a height of 40 cm above the sheet and the ink is droped.
• The size of the pattern formed this time by the ink drop is slightly higher than the first one.
• Finally, the dropper with ink in it is placed vertical at a height of 50 cm above the sheet and the ink is droped.
• The size of the pattern formed by the ink drop is the largest of al the others.
• Hence, The size of the pattern of the ink drop increases, when the vertical distance increases.
