Blocks `A and B` shown in the figure are connected with a bar of negligible weight. `A and B` each has mass `170 kg` , the coefficient of friction between `A` and the plane is `0.2` and that between `B` and the plane is `0.4 (g = 10 ms_(-2))`

What is the total force of friction between the blocks and the plane?

A

`900N`

B

`700N`

C

`600N`

D

`300N`
