Two bars of masses m, and m, connected by an light spring (intially at its natural length) rests on a horizontal plane. The coefficient of friction between the bars and the surface is `mu.` The mnimum costant force that bar to be applied in the horizontal direction (along the length of spring) to the bar of mass `m_(1)` in order to shift the other bar of mass `m_(2)` Acceleration due to gravity is g) will be

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)`
