Correct Answer - Option 3 : (-1/3, 8/3)

The correct answer is option 3) i.e. (-1/3,8/3).

CONCEPT:

  • Centre of mass: The point on a body where the whole of its mass is assumed to be concentrated is known as the center of mass of the body.
  • The X-coordinate and Y-coordinate of the centre of mass are given by:

\(X_{COM} = \frac{m_{1}x_{1}+m_{2}x_{2}}{m_{1}+m_{2}}\)

\(Y_{COM} = \frac{m_{1}y_{1}+m_{2}y_{2}}{m_{1}+m_{2}}\)

CALCULATION:

m= 1 kg, m= 2 kg, x= 1, x= -1, y= 2, y= 3

Putting the values in above formula we get,

Xcm = -1/3

Ycm = 8/3
