Two blocks of masses m(1) = 1 kg and m(2...

Two blocks of masses `m_(1) = 1 kg` and `m_(2) = 2 kg` are connected by a non-deformend light spring. They are lying on a rough horizontal surface. The coefficient of friction between the blocks and the surface is 0.4. What minimum constant force F has to be applied in horizontal direction to the block of mass `m_(1)` in order to shift the other block? `(g = 10 m//s^(2))`

A

`mu(m _(1) + m_(2))g `

B

`mu ( m _(1) + ( m _(2))/(2) ) g `

C

`mu ((m _(1))/(2) + m_(2))g`

D

`(mu ( m_(1) + m_(2)) g)/(2)`
