A block of mass `m_(1)` on a smooth, horizontal· swface is: connected to a second mass `m_(2)` by a light cord ovbr a light,: frictionless pulley as shown. (Neglect the mass of the cord and' of the pulley). A force of magnitude `F_(0)` is applied to mass `m_(1)`· as shown. Neglect any friction.

(a) Find the value of force `F_(0)` for which the sy!tem will be in equilibrium.
(b) Find the acceleration of masses andtensio~ in string if `F_(0)` has a value which is double of that foun,d in part (a).
