A wire of length 4m is made of a material of young's modulus `20times10^(11)Pa` .When the wire is extended by 1mm the stress developed in the wire is

A wire of length L and cross sectional area A is made of a material of Young's modulus Y. If the wire is streched by an amount x, the work done is………………

A wire of natural length l, young's modulus Y and ares of cross-section A is extended by x. Then, the energy stored in the wire is given by

A wire of length L and cross-sectional area A is made of material of Young's modulus Y. The work done in stretching the wire by an amount x is

The Young's modulus of the material of a wire is equal ot the

An iron wire of length 4 m and diameter 2 mm is loaded with a weight of 8 kg. if the Young's modulus Y for iron is 2xx10^(11)N//m^(2) then the increase in the length of the wire is

If a uniform brass wire of length 5 m and radius 10^(-3) m is extended by 10^(-3) m, then the energy stored in the wire will be (Young's modulus for brass =10xx10^(10)N//m^(2) )

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

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
