A body of mass 4kg is attached to another body of mass 2kg with a massless rod. If the 4kg mass is at (2i+5j)m and 2kg mass is at (4i+2j)m, the centre of mass of the system is at (in m)

A body of mass 4kg is attached to another body of mass 2kg with a mass

1.	A body of mass 4kg is attached to another body of mass 2kg with a massless rod. If the 4kg mass is at (2i+5j)m and 2kg mass is at (4i+2j)m, the centre of mass of the system is at (in m)
Answer» `8i+12j` `(1)/(2)(8i+12j)` `(1)/(3)(8i+12j)` `(1)/(4)(8i+12j)` Answer :C
