Two wires each of radius 0. 2 cm and negligible mass, one made of steel and the other made of brass are loaded as shown in the figure. The elongation of the steel wire is______10 -6 m. [Young's modulus for steel = 2 x 10 11 N m -2 and g = 10 m s -2 ]
Text Solution
Verified by ExpertsThe correct answer is:
20
(20)
The force acting on steel wire F is (2 + 1.14) g = 3.14g
From the relation of Young's modulus, it can be written
