Question

Four bodies have been arranged at the corner of a rectangle find the coordinates of the centre of the mass of system

Answer 1

The arrangement of the centre of mass is 3a / 5, 7b / 10 respectively.

Step-by-step explanation:

Therefore  centre of mass at x coordinate:

xcm = x1m1 + x2m2 + x3m3 + x4m4 / m1 + m2 + m3 + m4

      = 3a / 5

And centre of mass at y coordinate:

ycm = y1m1 + y2m2 + y3m3 + y4m4 / m1+m2+m3+m4

      = 7b / 10

Hence the arrangement of the centre of mass is 3a / 5, 7b / 10 respectively.
