Question:
A particle of mass 5 kg is attached to one end of a light elastic string of natural length 0.8 m. The other end of the string is attached to a fixed ceiling and the particle is allowed to rest, hanging in equilibrium. If the string is stretched by an additional 80%, determine the modulus of elasticity. Hence find the elastic potential energy stored in the string.
