Question

State the position of centre of gravity in case of the following regular bodies,
(i) triangular lamina
(ii) a sphere
(iii) square lamina

Answer 1

Answer:

For regular shaped bodies centre of gravity lies in the centre of the particular body. Hence for triangular lamina centre lies at the centroid which is the intersection of the three lines drawn from the vertex to the midpoint of the opposite side. Hence centre of gravity lies at the intersection of the three medians.

Answer 2

a sphere is the answer

the position of centre of gravity in case is sphere
