1 kg and 4 kg blocks lie on a rough hori...

`1 kg` and `4 kg` blocks lie on a rough horizontal surface. The coefficient of friction between `4 kg` blocks and surface is `0.2` while the coefficient of firction between `1 kg` blocks and the surface is `0.6`. All the pulley shown in the figure are massless and frictionless and all strings are massless and frictionless and all strings are massless.

A

The frictional force acting on `1 kg` blocks is `2N`.

B

The frictional force acting on `1 kg` block is `6N`

C

The tension in the string connecting `4 kg` block and `1 kg` blocks is `1N`

D

The tension in the string connecting `1 kg` block and `4 kg` blocks is zero.

Text Solution
