Assuming that the block is always remains horizontal, hence the acceleration of B is –

A

6 m/s2

B

2 m/s2

C

4 m/s2

D

None of these

Answer

2 m/s2

Explanation

Solution

aA = 6aB

aB = aA6\frac { \mathrm { a } _ { \mathrm { A } } } { 6 } = 12 m/s26\frac { 12 \mathrm {~m} / \mathrm { s } ^ { 2 } } { 6 } = 2m/s2
