Question

# If stress is numerically equal to young's modulus,the elongation will be

A
1/4 the original length
B
1/2 the original length
C
equal to the original length
D
Twice the original length

Solution

## The correct option is C equal to the original lengthThe ratio of stress to strain is known as the elastic modulus of the material.Elastic Modulus, $$E=\dfrac{stress}{strain}$$When the change in elongation to the original length is minimal, then the modulus of elasticity is dimensionally equivalent to the stress.Physics
