139847 The velocity of projection of a body is increased by \(2 \%\). Other factors remaining unchanged, what will be the percentage change in the maximum height attained?

139848 A wire has a mass \((0.1 \pm 0.001) g\) radius \((0.5 \pm\) \(0.005) \mathrm{mm}\) and length \((10 \pm 0.1) \mathrm{cm}\). The maximum percentage error in the measurement of its density is.

139849 A student measured the diameter of a small steel ball using a screw gauge of least count \(0.001 \mathrm{~cm}\). The main scale reading is \(5 \mathrm{~mm}\) and zero of circular scale division coincides with 25 divisions above the reference level. If screw gauge has a zero error of \(-0.004 \mathrm{~cm}\), the correct diameter of the ball is

139850 The density of a material in the shape of a cube is determined by measuring three sides of the cube and its mass. If the relative errors in measuring the mass and length are respectively \(1.5 \%\) and \(1 \%\), the maximum error in determining the density is
