1 In this question use \(g = 10 \mathrm {~m} \mathrm {~s} ^ { - 2 }\)
A particle of mass 2 kg is attached to one end of a light elastic string of natural length 0.5 metres and modulus of elasticity 100 N . The other end of the string is attached to the point \(O\). Find the extension of the elastic string when the particle hangs in equilibrium vertically below \(O\). Circle your answer.
