Question
A brass rod of cross-sectional area 1 cm2 and length 0.2 m is compressed lengthwise by a weight of 5 kg. If Young′s modulus of elasticity of brass is 1 × 1011 N/m2 and g = 10 m/ sec2, then increase in the energy of the rod will be : -
Options
A.10-5 joule
B.2.5 × 10-5 joule
C.5 × 10-5 joule
D.2.5 × 10-4 joule
= 2.5 × 10-5 JMore Momentum and Collision Questions
