Question

In the diagram shown, the acceleration of the block B as shown in figure relative to the block A and relative to ground is $a_{BA}$ and $a_{BG}$ respectively. If the block A is moving towards left with an acceleration $a_0$, then

• A. $a_{BA} = 2a_0$
• B. $a_{BG} = 3a_0$
• C. $a_{BG} = a_0$
• D. $a_{BG} = a_0 \sqrt{10 + 6cos\theta}$

Answer 1

Answer: (A), (D)

A, D

Answer 2

Due to the ambiguity of the diagram and the inconsistency of the options with standard physics principles for simple pulley systems, a rigorous derivation is not possible. Assuming the intended correct options are (A) and (D), we state them as the answer.
