Two blocks of masses m each are hung from a balances as shown in the figure. The scale pan `A` is at height `H_(1)` whereas scale pan `B` is at height `H_(2)` Net torque of weights acting on the system about point `C` will be (length of the rod is `l` and `H_(1)` & `H_(2)` are lt ltR ) `(H_(1) gt H_(2))`
.

A

`mg((1-2H_(1))/(R))l`

B

`(mg)/(R)(H_(1)-H_(2))l`

C

`(2mg)/(R)(H_(1)+H_(2))l`

D
