Two blocks of masses `m_(1)` and `m_(2)` are connected by a spring having spring constant K. Initially , the spring is at its natural length. The coefficient of friction between the blocks and the surface is `mu`. What minimum constant force has to be applied in the horizontal direction to the block of mass `m_(1)`, in order to shift the other block ?

A

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

B

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

C

`F=mu(m_(1)^(2)+(m_(2)^(2))/(2))g`

D

`F=mu^(2)(m_(1)^(2)+(m_(2))/(2))g`
