Question

Centre of gravity of a rectangle will be at its:
A) Centre
B) At its periphery
C) Intersection of its diagonal
D) None

Answer 1

Hint: In order to solve this question you have to know the concept of centre of gravity. Basically, the centre of gravity of an object is defined as the point at which the mass of the object is evenly distributed and all sides are also in balance.

Complete answer:
The Center of gravity is defined as the point from which the mass of a body or system is balanced and evenly distributed whereas the centre of mass is the point at which the distribution of mass is equal in all directions and doesn’t rely on the gravitational field.

The position of the centre of gravity is an important parameter which determines the flight characteristics of an object. The centre of gravity of a rectangle is at the point at which the diagonals of that rectangle intersects.

Additional information: The centre of gravity of a triangle is at the point where the medians of the triangle meet. The centre of gravity of a square, parallelogram or rectangle is at the points where its diagonals intersect each other and the centre of gravity of a circle is at its centre. The centre of mass of the human body depends on the limbs and gender of the human.

Note: The location of the centre of gravity of an object affects its stability. The lower the centre of gravity of an object, the higher the stability and the higher is the centre of mass, the more an object is to topple over if it is tilted. Remember that in most mechanics problems, the gravitational field is assumed to be uniform.
