Three bodies each of mass 1 ~kg are situated at the vertices of an equilateral triangle of side 1 ~m . The x y -coordinates of centre of mass of the system are.

Options

  1. A( 1 2 3 , 1 2 3 )
  2. B( 1 2 3 , 1 2 )
  3. C( 1 2 , 1 2 )
  4. D( 1 2 , 1 2 3 )

Correct answer

D. ( 1 2 , 1 2 3 )

Step-by-step solution

aligned & X_ cm = 0+(1 1)+(1 0.5) 3 = 1 2 ~m & Y_ cm = 0+0+ (1 3 2 ) 3 = 1 2 3 ~m aligned
