.
Final Answer : (B)
Concepts Involved :
1) Pulley Constraint or
2) Length Constraint
By Pulley Constraint , we can say
[tex] a_2= \frac{0+a_1}{2}// //
=> 2a_2 = a_1 .
This can also be said by looking at tge tensions in the string ,in which one string is has magnitude double of another .
Hence, 2a_2=a_1
