An object of mass m initially at rest on a smooth horizontal plane starts moving under a force F = 2 N. During its motion, the angle θ between the force and horizontal varies as θ = kx, where k is a constant and x is the distance from the initial position. The kinetic energy is E = (n/k) sinθ. The value of n is:
