Read the following statements below carefully and state, with reasons, if it is true or false.
The stretching of a coil is determined by its shear modulus.

उत्तर
True
Shear modulus is the ratio of the applied stress to the change in the shape of a body. The stretching of a coil changes its shape. Hence, the shear modulus of elasticity is involved in this process.
