Find distance of centre of mass of solid hemisphere of radius 8cm from centre

Determine the centre of mass of a uniform hemisphere of radius R.

What can be said about the centre of mass of a solid hemisphere of radius r without making any calculation. Will its distance from the centre be more than r//2 or less than r//2 ?

Find the centre of mass of a uniform solid cone.

From a uniform circular disc of mass M and radius R a small circular disc of radius R/2 is removed in such a way that both have a common tangent. Find the distance of centre of mass of remaining part from the centre of original disc.

A circular hole is cut from a disc of radius 6 cm in such a way that the radius of the hole is 1 cm and the centre of 3 cm from the centre of the disc. The distance of the centre of mass of the remaining part from the centre of the original disc is

Charge Q is uniformly distributed throughout the volume of a solid hemisphere of radius R metres. Then the potential at centre O of hemisphere in volts is:

Calculate the gravitational field intensity and potential at the centre of the base of a solid hemisphere of mass m , radius R

What is the distance of centre of mass of a half fring from centre if the ring has radius =0.5 m [XI]

From a circular disc of radius R , a triangular portion is cut (sec figure). The distance of the centre of mass of the remainder from the centre of the disc is -

A disc of radius r is cut from a larger disc of radius 4r in such a way that the edge of the hole touches the edge of the disc. The centre of mass of the residual disc will be a distance from centre of larger disc :-
