Question

Which of the following wrongly represents the position of centre of gravity of the given objects?

पर्याय

• Object	Position of centre of gravity
  Rod	Rate of doing work by a body is called power.

• Object	Position of centre of gravity
  Circular disc	Geometric centre

• Object	Position of centre of gravity
  Solid sphere	Geometric centre of the sphere

• Object	Position of centre of gravity
  Cylinder	Axis of cylinder

Answer 1

Object	Position of centre of gravity
Rod	Rate of doing work by a body is called power.

Explanation:

For a uniform rod, the centre of gravity lies at its midpoint.

The statement given for the rod, “Rate of doing work by a body is called power,” is unrelated to centre of gravity, so it is wrongly represented.
