6.The total elongation produced in a bar of uniform section hanging vertically downwards due to its own weight is equal to that produced by a weight

of same magnitude as that of bar and applied at the lower end
half the weight of bar applied at lower end
half of the square of weight of bar applied at lower end
one-fourth of weight of bar applied at lower end
