How can I get the elongation if I'm given with only the modulus of elasticity?
what will be the formula?

THnx..

Are you talking about the extension of a spring? (Hooke's law?)

Hooke's law is $F = kx$

where F is the force applied to the spring, k is the modulus (spring constant), and x is the extension of the spring from its natural length.
