Question

A clock wall uses a vertical spring-mass system to measure the time. Each time the mass reaches an extreme position, the clock advances a second. The clock gives the 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. gives the correct time.

Answer 1

The correct option is D gives the correct time.

As the Time period of Spring mass system is given by:

$T=2\pi \sqrt{\frac{m}{k}}$

Time period does not depend on the acceleration due to gravity .So Clock gives correct time at poles also.

Option D is correct.
