A projectile which starts from the surface of the Earth at the sea level is launched with the initial speed of #v_0 = sqrt(GM_âŠ•/R_âŠ•)# and with the projecting angle (with respect to the local horizon) of #Î¸ =Ï€/6# What is the maximum height of projectile?

Actually I found another source which says it does change. Here's the explanation. When the bob is full, the CM is at the centre of the bob. As the water falls, the CM lowers thus increasing the 'effective length' of the pendulum. Thus changing the period.

The hollow metallic bob of a simple pendulum is filled with water. Water comes out drop by drop through a small hole at the bottom of the bob. How will the time period change?
