The centre of mass of a solid hemisphere of radius 8   cm is x   cm from the centre of the flat surface. Then value of x is

Correct answer

3

Step-by-step solution

Centre of Mass of a solid hemisphere from centre of the flat surface is given by, h cm = 3 R 8 It is given that R =   8   c m Therefore, x = h c m = 3 R 8 = 3 × 8 8 x = 3   c m
