1.	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
Answer» `mu(m _(1) + m_(2))G ` `mu ( m _(1)+ ( m _(2))/(2) ) g ` `mu ((m _(1))/(2) + m_(2))g` `(mu ( m_(1) + m_(2)) g)/(2)` ANSWER :B
