Three point particles of masses $1.0 \mathrm{k}\mathrm{g}, 1.5 \mathrm{kg}$ and $2.5 \mathrm{k}\mathrm{g}$ are placed at three corners of a right angle triangle of sides $4.0 \mathrm{c}\mathrm{m}, 3.0 \mathrm{c}\mathrm{m}$ and $5.0 \mathrm{c}\mathrm{m}$ as shown in the figure. The centre of mass of the system is at a point:

• A

  $0.6 \mathrm{c}\mathrm{m}$ right and $2.0 \mathrm{c}\mathrm{m}$ above $1 \mathrm{k}\mathrm{g}$ mass.
• B

  $1.5 \mathrm{c}\mathrm{m}$ right and $1.2 \mathrm{c}\mathrm{m}$ above $1 \mathrm{k}\mathrm{g}$ mass.
• C

  $2.0 \mathrm{c}\mathrm{m}$ right and $0.9 \mathrm{c}\mathrm{m}$ above $1 \mathrm{k}\mathrm{g}$ mass.
• Correct answer
  D

  $0.9 \mathrm{c}\mathrm{m}$ right and $2.0 \mathrm{c}\mathrm{m}$ above $1 \mathrm{k}\mathrm{g}$ mass.

Hence, the correct answer is option: 'D'.
