Question

three identical metal balls each of radius r are placed touching each other on a horizontal surface such that an equilateral triangle is formed when the centres of three balls are joined at the centre of mass of the system is located at "point of intersection of median" HOW?​

Answer 1

Answer:

Explanation:

In the triangle LMN it may be divided into narrow strips as LM,MN,NL. By symmetry each strip has its center of mass at its midpoint. If we join the midpoint of all strips we get the median LP,MQ,NR. This means the centre of mass lies on the point of concurrence of the medians that is on the centriod G

Answer 2

Answer:

When three identical metalic balls of equal radius 'r' placed touchinge each other then it form an equilateral triangle of side 2r

And it is know that centre of mass lies in middle centre for symmetrical objects so centre of mass lies at the point of intersection of median
