Determine the CM of a uniform solid cone of height h and semiangle ` infty` as shown in fig 4E . 31

In Fig. 16.74, from the top of a solid cone of height 12 cm and base radius 6 cm, a cone of height 4 cm is removed by a plane parallel to the base. Find the total surface area of the remaining solid. (U s e\ \ pi=22//7\ \ a n d\ \ sqrt(5)=2. 236) (FIGURE)

A charge q is placed at a height (h)/(4) from the base of a cone of height h and radius R as shown in figure. Calculate the flux linked with the curved surface of the cone.

A frustum of a uniform solid cone has base radius R and height H as shown. Radius of top surface is (R )/(2) . If height of centre of mass of frustum is (11H)/(4n) from base then n will be.

Locate the position of centre of mass of a uniform plate of Mass m as shown in fig 4E 34

A uniform solid right circular cone of base radius R is joined to a uniform solid hemisphere of radius R and of the same density, as shown. The centre of mass of the composite solid lies at the centre of base of the cone. The height of the cone is

A solid metallic cylinder of base radius 3 cm and height 5 cm is melted to make n solid cones of height 1 cm and base radius 1 mm. The value of n is
