Question
A man having a wrist watch and a pendulum clock rises on a TV tower. The wrist watch and pendulum clock per chance fall from the top of the tower. Then
- Both will keep correct time during the fall.
- Both will keep incorrect time during the fall.
- Wrist watch will keep correct time and clock will become fast.
- Clock will stop but wrist watch will function normally.
The correct answer is: Clock will stop but wrist watch will function normally.
Function of wrist watch depends upon spring action so it is not effected by gravity but pendulum clock has time period, 
. During free fall effective acceleration becomes zero, so time period comes out to be infinity i.e. the clock stops
