Find the elongation produced in a copper wire of length 2m and radius 5mm, when suspended by a block
of mass 500kg. (take young's modulus of elasticity of copper y = 1,2 ×109 pa).

Aliquid is an answer i hope this

The modern-day generator works on the principle of electromagnetic induction discovered by michael faraday in 1831-32. faraday discovered that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field.
