ExamVeda will never Correct THIS Question!
Question is not completed
Some mistake in this option
E repeated two times
But right answer is
M/I = E/R = F/Y
f/y correct
in option C > there are two times E, it's neglected each other.
M/I =F/Y=E/R
Hey it should be F/Y
M/I=E/R=F/Y is the correct equation.
But the question and answer isn't clear.
here is no one option are correct because according to the bending equation
M/I = E/R = F/Y
Actually, option 3 is don't have any stress term (F)
