Question

You place a mass of 250 grams on the measurement tray of a triple beam balance and then set the rider on the 500 gram beam to the 200 gram mark (the other riders are set to 0 grams). Which of the following statements is true?

A. The pointer will be above the zero mark.
B. The pointer will be below the zero mark.
C. The pointer will be lined up with the zero mark.
D. The pointer will move up and down once per second.

Answer 1

Correct answer is option A (The pointer will be above the zero mark)

Step-by-step explanation:

since the mass of 250 grams is placed on the measurement tray of a triple beam balance and the rider is set to 500 gram beam to the 200 gram mark and the other riders are set to 0 grams at that time the pointer will be above the zero mark.

Hence when we place a mass of 250 grams on the measurement tray of a triple beam balance and then set the rider on the 500 gram beam to the 200 gram mark (the other riders are set to 0 grams) that time the pointer will be above the zero mark.

hence correct answer is option A
