An object of mass 'm' initially at rest on a smooth horizontal plane starts moving under the action of force F = 2N. In the process of its linear motion, the angle 
(as shown in figure) between the direction of force and horizontal varies as 
= kx, where k is a constant and x is the distance covered by the object from its initial position. The expression of kinetic energy of the object will be E = 
. The value of n is ____.
