A block of mass 1 kg is placed on a rough
horizontal surface. A force of 20 N is start to act
on block as shown in figure. Coefficient of
friction between surface of block and horizontal
surface is 0.5. The friction force on block is

The length of a rectangle is given as (L ± l) and
its width as (W ± w). Where l and w are small,
so that product lw are very small and can be
ignored -
(A) uncertainty in its area is Lw
(B) fractional uncertainty in the area is W/l+l/w
(C) uncertainty in its area is (Ll + wW) A block is placed on a surface with vertical cross
section given by the equation y = x^2/20

without slipping is -
(A) 1.00 m (B) 1.25 m
(C) 1.50 m (D) 1.90 m
