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
(a) run slow
(b) run fast
(c) stop working
(d) give correct time

Answer 1

(d) give correct time

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