In the figure, blocks A, B and C of mass m each have acceleration a1, a2 and a3 respectively. `F_(1)` and `F_(2)` are external forces of magnitudes 2mg and mg respectively, then :

A

`a_(1) = a_(2) = a_(3)`

B

`a_(1) gt a_(2) gt a_(3)`

C

`a_(1) = a_(2), a_(2) gt a_(3)`

D

`a_(1) gt a_(2), a_(2) = a_(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
`a_(1) = (2mg - mg)/(m) g, a_(2) = (2mg - mg)/(3m) = (g)/(3)` and `a_(3) = (mg - mg)/(m) = 0` `:. a_(1) gt a_(2) gt a_(3)`
