Which of the following rods of same material undergoes maximum elongation when subjected to a given force?
Options
(a) l=1 m, d=2 mm
(b) l=2 m, d=1 mm
(c) l=1 m, d=1 mm
(d) l=2 m, d=2 mm
Correct Answer:
l=2 m, d=1 mm
Explanation:
Δl(elongation) = Fl/YA
F is same. Young modulus is same.
.·. Δl α 1/r² .
