Question

A seconds' pendulum is taken to a place where
acceleration due to gravity falls to one-fourth. How
is the time period of the pendulum affected, if at
all ? Give reason. What will be its new time period ?
Plz help me. ​

Answer 1

Answer:

The time period is affected by acceleration due to gravity. 

The relation given below clearly states that:

Tαg1, 

Time period is inversely proportional to the square root of acceleration

 due to gravity. 

Hence, when 'g' falls one-fourth, time period increases, it doubles.

Hence the new time period is  2×2

=4s.
