In the adjacent figure, all the pulleys are frictioniess and massless, all the stringes are also massless. The relation between `a_(1),a_(2)` and `a_(3)` is (where `a_(1),a_(2)` and `a_(3)` are the acceleration of masses `m_(1),m_(2)` and `m_(3)` respectively in the direction as shown in the figure)

Options

A. `a_(3)-a_(2)+2a_(1)=0`
B. `a_(3)+a_(2)-2a_(1)=0`
C. `2a_(2)+a_(3)=2n_(1)`
D. None of these

Explanation

`2Ta_(1)-Ta_(2)+Ta_(3)=0`
`rArr2a_(1)-a_(2)+a_(3)=0`
