If the ratio of lengths, radii and Young's modulus of steel and brass wires shown in the figure are a, b, and c, respectively. The ratio between the increase in lengths of brass and steel wires would be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Given, 
Let Young's modulus of steel be 
, and that of bras be 
……… (i)
and 
…… ..(ii)
Dividing equation (i) by equation (ii), we get
…… (iii)
Force on steel wire from free body diagram
Newton
Force on brass wire from free body diagram
Newton
Now putting the value of 
in Equation (iii), we get
