उत्तर
1. For a hollow cone, the position of center of gravity is at a height of `h/3` from the base on its axis.
So, position of center of gravity from broad base = `h/3`
= `6/3`
= 2 cm
2. Yes, now cone is a solid cone. So, the position of the new center of gravity from the base will be `h/4 cm "i.e.," 6/4 = 1.5 cm` from the base of the cone.
