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 tabel as in the figure. The tension `T_(1)` and `T_(2)` are also indicated
.
a) `T_(2)gtT_(1)` if `m_(2)gtm_(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` .
