Three blocks A, B and C are arranged as shown in the figure such that the distance between two successive blocks is 10 m. Block $A$ is displaced towards block $B$ by 2 m and block C is displaced towards block B by 3 m. The distance through which the block B should be moved so that the centre of mass of the system does not change is

• A

  1.4 m, towards block C
• B

  1.5 m, towards block A
• C

  2 m, towards block A
• Correct answer
  D

  1 m, towards block C

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