Which of the given sources of errors will NOT affect your readings while handling the Gravesand's apparatus?
Correct answer: A. Friction in the pulleys
- A. Friction in the pulleys
- B. Use of rusty holding pins
- C. Use of inaccurate weights
- D. Placement of the drawing board
Explanation
Friction in the pulleys is the correct answer because it directly impacts the smooth movement of the apparatus, affecting the accuracy of the readings. The other options, such as rusty holding pins, inaccurate weights, and the placement of the drawing board, can all introduce errors but may not necessarily be exclusive to Gravesand's apparatus or have the same direct impact on readings.
