A steel wire is 4.0 m long and 2 mm in diameter. Young’s modulus of steel is 1.96 xx 10^(11) N//m^(2) . If a mass of 20 kg is suspended from it the elongation produced will be-

If the young's modulus of the material of the rod is 2 xx 10^(11) N//m^(2) and its density is 8000 kg//m^(3) then the time taken by a sound wave to traverse 1m of the rod will be

The radius of the earth is 6.37 xx 10^(6) m and its mean density is 5.5 xx 10^(3) "kg m"^(-3) and G = 6.67 xx 10^(-11) "N-m"^(2) kg^(-2) Find the gravitational potential on the surface of the earth.
