Question
A wall clock uses a vertical spring-mass system to measure the time. Each time the mass reaches an extreme position, the clock advances by a second. The clock gives correct time at the equator. If the clock is taken to the poles it will:
  1. Run slow.
  2. Run fast.
  3. Stop working.
  4. Give correct time.

Answer

  1. Give correct time.

Explanation:

Because the time period of a spring-mass system does not depend on the acceleration due to gravity.
