A body of mass 1 kg rests on a horizontal floor with which it has a coefficient of static friction 1 3 . It is desired to make the body move by applying the minimum possible force F N . The value of F will be _______.(Round off to the Nearest Integer) [Take g = 10 m s - 2 ],

F cos θ = μ N ⇒ F sin θ + N = m g ⇒ F = μ mg cos θ + μ sin θ F min = μ m g 1 + μ 2 = 1 3 × 10 2 3 = 5
