A wire elongates by 8 mm when a load of 9 kg is suspended from it. What is the elongation when its radius is doubled, if all other quantites are the same as before ?

A wire elongates by l units, when a load w is suspended from it . If the wirew gets over a pulley ( equally on both the sides ) and two weights w each are hung at the two ends, the elongation of wire (in units ) will be

A wire gets elongated by 4 mm when a block of mass 2 kg is suspended from it. Now, the block is immersed in water, the wire contracts by 1 mm. Find the density of block when the density of water is 1000kg//m^(3) .

A spring elongates by 2 cm when a piece of cobalt of mass 20g is suspended from it. A water conatiner is placed below the pieces in such a way that the piece is immersed completely in water. Calculate the elongation produced in the spring. Density of cobalt =8700 "kg/m"^(3), Use g=10m/s^(2) .
