Why do the pendulum clocks go slow in summer and fast in winter?

Text Solution

Verified by Experts

Time period of pendulum =T=`2pisqrt((l)/(g))or T xxsqrt(l)`
In winter I becomes shorter so its time period reduces so it goes faster. In summer I increases resulting in increase in time period so the clock goes slower.
