Answer :

The map of India is irregular in shape its center of gravity can be found out in following way


1. Take the map and make three holes along its edge.


2. Suspend the map freely from one hole by using the thread as shown in the figure below.



3. Take a plumb bob and suspend it from the same hole.


4. Draw a line along the thread. It indicates the line of weight at that point. As shown in the figure below.



5. Repeat the same from remaining holes and draw other two lines of weight.


6. The concurrent point of the three lines is the Center of gravity of the map.
