Question

A sphere of radius R and mass M if R/2 part cut of from sphere. Find mass of cut part and remaining part.​

Answer 1

Answer:

Density of sphere before cutting =M/4/3πR^3

Mass of hemisphere after cutting

M=volume *Density

2/3πR^3*M/4/3πR^3

=M/2

Answer 2

Answer:

density of sphere before cutting =M/4/3πR^3

mass of sphere after cutting

mass=v×d

2/3πR^3×M/4/3πR^3

m=M/2
