Question 1

Four different experimental setups used in physics investigations are described below:

  • Setup A: A wooden block is pulled linearly up a slanted ramp by a string attached to a newtonmeter.
  • Setup B: A vertical helical spring is suspended from a stand with a weight hanger hanging downward, causing linear extension.
  • Setup C: A metre rule rests on a triangular pivot at its centre, with a mass placed on the left-hand side causing the rule to tilt downwards about the pivot.
  • Setup D: A ray of light refracts as it passes through a rectangular glass block.

In which of these setups does an applied force cause rotation?

A

Setup A (wooden block on a ramp)

B

Setup B (weighted spring on a stand)

C

Setup C (metre rule on a pivot)

D

Setup D (refraction through a glass block)
