Where is the center of gravity of the pendulum bob ?
In the picture , is just a pendulum itself , the center of gravity is in the middle of the pendulum as you can see , in my drawing , it is not exactly accurate .
In this second picture , it is a pendulum with plasticine on top , the position of the center of gravity would be higher .
In this third picture , the plasticine is completely wrapped around the pendulum (take that the plasticine is wrapped and covered equally) , the center of gravity would be in the center like the first picture .
In this last picture , there's a hole in the middle , the center of gravity ... I'm guessing that it would still be in the middle .

In class , Mr Lim asked us to find out where's the center of the gravity on each of the pendulum respectively . All 3 'pendulums' were done by yours truly :D Despite my ugly and not exactly very accurate drawings i hope you can get an idea of what this is about , even if they look like eggs ;P .
