Consider three blocks of masses `m_(1), m_(2), m_(3)` interconnected by strings which are pulled by a common force F on a frictionless horizontal table as in the figure. The tension `T_(1) and T_(2)` are also indicated

a) `T_(2) gt T_(1)" if "m_(2) gt m_(1)`
b) `T_(2) =T_(1)" if "m_(2)=m_(1)`
c) `T_(2) gt T_(1)` always
d) `"acceleration of the system"=(F)/(m_(1)+m_(2)+m_(3))`

Options

A. a, b
B. b, d
C. a, d
D. c, d

Answer

D

Explanation

`F=ma a=(F_("net"))/(M), T_(1)=m_(1)a, T_(2)=(m_(1)+m_(2))a`
