The centre of mass of three particles of masses 1 kg, 2kg and 3kg is at (2, 2, 2). The position of the fourth mass of 4 kg to be places in the system as that the new centre of mass is at (0, 0, 0) is

View answer and explanation

Correct option: A

\left( { - 3, - 3, - 3} \right)

Option A ((-3, -3, -3)) is correct because the position of the fourth mass is calculated using the center of mass formula to achieve a new center of mass at (0, 0, 0).
