Figure shows two blocks A and B connected to an ideal pulley string system. In this system when bodies are released then: (neglect friction and take g = 10 $m/s^2$)

 

• A

  Acceleration of block A is 1 $m/s^2$

• B

  Acceleration of block A is 2 $m/s^2$

• C

  Tension in string connected to block B is 40 N

• D

  Tension in string connected to block B is 160 N
