Question

The centre of gravity of a body of irregular shape lies A at its centre b at the intersection of medians C at the intersection of diagonals D at the surface of the body E at the axis of rotation of the body​

Answer 1

Answer:

At the point of intersection of its medians.

Explanation:

Centre of gravity means a point from which the weight of a body or system may be considered to act. In uniform gravity it is the same as the centre of mass. 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.
