Two blocks rest on a horizontal friction...

Two blocks rest on a horizontal frictionless surface as shown in the figure. The surface between the top and bottom blocks is roughened so that there is no slipping between the two blocks. A 30-N force is applied to the bottom block as suggested in the figure.

B

`0.05`

C

`0.20`
