Question

Where is the centre of gravity of the following objects situated? l. Ring 2. Rhombus 3. Scalene triangle 4. Cylinder.

Answer 1

The location of the centre of gravity of the following objects are as follows-

• Ring : The centre of gravity of a circular ring is situated at the centre of the circle by which the ring is formed.
• Rhombus : The centre of gravity of a rhombus is situated at the intersection point of the two diagonals of the rhombus.
• Scalene triangle : The centre of gravity of a scalene triangle is situated at the centroid of that scalene triangle.
• Cylinder : The centre of gravity of a cylinder is situated at the midpoint of the vertical axis of the cylinder.

Answer 2

Answer:

(i) Ring:- Center of gravity is at the centre of ring.

(ii) Rhombus:- Center of gravity is at point of intersection of diagonal.

(iii) Scalene Triangle:- Center of gravity is the at point of intersection of median.

(iv) Cylinder:- Center of gravity is at midpoint on the axis of cylinder.
