A 20 N stone is suspended from a wire and its length changes by `1%`. If the Young's modulus of the material of wire is `2xx10^(11)N//m^(2)`, then the area of cross-section of the wire is `2xx10^(11)N//m^(2)`, then the area of cross-section of the wire will be

A 20 N stone is suspended from a wire and its length changes by 1% . If the Young's modulus of the material of wire is 2xx10^(11)N//m^(2) , then the area of cross-section of the wire will be

A wire suspended vertically from one of its ends is stretched by attaching a weight of 20 N to its lower end. If its length changes by 1% and if the Young's modulus of the material of the wire is 2 xx 10^(11) N//m^(2) , then the area of cross section of the wire is

If young's modulus of steel is 2xx10^(11)N//m^(2) , then the force required to increase the length of a wire of cross section 1 cm^(2) by 1% will be

When a load of 10 kg is hung from one end of a wire of length 5 m, the wire elongates by 5 mm. IF the young modulus for the material of the wire is 9.8 times 10^10 N.m^-2 , then find the area of cross section of the wire. [g=9.8 m.s^-2 ]

The Young's modulus of the material of a wire is 2xx10^(10) N m^(-2) If the elongation strain is 1% then the energy stored in the wire per unit volume is J m^(-3) is

A wire of length 1m is stretched by a force of 10N. The area of cross-section of the wire is 2 × 10^(–6) m^(2) and Y is 2 xx 10^(11) N//m^(2) . Increase in length of the wire will be -

The Young's modulus of the material of a wire is 2xx10^(10) N m^(-2) If the elongation strain is 1% then the energy stored in the wire per unit volume in J m^(-3) is
