Hi, Do you know the formula to calculate Time period of a pendulum ?

Hint:
Melting of Ice reduces its weight.

formula of time period is T=2*pi root over l/g
so how does reduction of weight helps out?....i mean time period is not dependant on mass and gravity remains constant at a particular place (weight =mg)...???

That is the trick.You almost got it.

Not sure how that's a hint.

The period of the pendulum is independent of the bob mass. Ah, Galileo's wonderful discoveries.

Seems you did not read my next post :p

so if g remains constant...then there is no effect on time period????

nopes.

okie dokie....thank you....
