In fig the blocks A,B,and C of mass m each have acceleration `a_(1),a_(2), and a_(3)`, repectively. `F_(1) and F_(2)` are external force of magnitude `2mg and mg`, respectively. Then

A

`a_1 != a_(2) != a_(3)`

B

`a_1 = a_(2) != a_(3)`

C

`a_1 gt a_(2) gt a_(3)`

D

`a_1 != a_(2) = a_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A, C
`a_(1)=(2mg-mg)/(m)=g`
`a_(2)=(mg+mg-mg)/(2m)=g//2`
`a_(3)=(2mg-mg)/(3m)=g//3`
Clealy `a_(1) gt a_(2) gt a_(3)`.
