Question

Arrange the following steps of an experiment in sequential order to show that the body moves with uniform velocity.

• A. B C E F A D G
• B. A B C E G F D
• C. A C B D F G E
• D. B C A D F E G

Answer 1

The correct option is D

B C A D F E G

Explanation for correct answer:

Steps of an experiment in sequential order to show that the body moves with uniform velocity:

1. Spread a sheet of white paper on a horizontal table.
2. Arrange a trolley with an ink dropper attached to it.
3. Take a long thread and tie one end of it to a trolley and the other end of it to the second hand of a clock.
4. Place the whole arrangement on the table.
5. When the trolley driven by the clock moves forward, ink drops fall on the paper at regular intervals.
6. Measure the distance between successive drops and note the time intervals between the drops.
7. Calculate the ratio of the distance between the successive drops to the time and it is observed that the ratio remains constant.

Hence, the correct sequential order is B C A D F E G.

Thus, option (D) is correct.
