An irregular lamina is suspended successively from two different points A and B. The vertical lines drawn through the points of suspension intersect at point G. This intersection point G represents the:

  1. A
    point of maximum moment of inertia of the lamina.
  2. B
    centre of gravity of the lamina.
  3. C
    point where the angular velocity is always zero.
  4. D
    point of zero gravitational potential energy.
View Answer & Solution

Correct answer · Option B

centre of gravity of the lamina.

Explanation

When a body is freely suspended, its centre of gravity must lie on the vertical line passing through the point of suspension to produce zero gravitational torque. Thus, the intersection of two such lines uniquely identifies the centre of gravity.
