  • The image shows a newton meter which has a spring inside it. Why is a spring used in the newton meter?
    The image shows a newton meter which has a spring inside it. Why is a spring used in the newton meter?
    • The spring stops the hook from moving.
    • The spring stretches more when there is a larger force on it.  ✓
    • The spring stretches less when there is a larger force on it.
    • The spring makes the meter strong enough to hold things.
  • The picture shows a steel paperclip on some thread being attracted by a magnet. The paperclip is stationary. Which statements must be true?
    The picture shows a steel paperclip on some thread being attracted by a magnet. The paperclip is stationary. Which statements must be true?
    • There is an upwards magnetic force acting on the paperclip.  ✓
    • The downwards gravitational force is equal to the upwards magnetic force.
    • There is downwards force on the paperclip due to tension in the thread.  ✓
    • The tension in the thread is equal to the upwards magnetic force.
    • The upwards and downwards forces are equal so there is no resultant force.  ✓
