Two blocks A and B are lying on the table as shown in the figure. The coefficient of friciton between block A and block B is `mu`. The coefficient of friction between block B and ground also `mu`. An external force F is applied in the direction shown. The maximum value of the force F that can be applied without moving the blocks.

`mu( 2 m_(A) + m_(B)) g`

`mu( m_(A) + m_(B))g`

`mu(2m_(A) + m_(B)//2)g`

`mu(3m_(A) + m_(B))g`
