A rod of mass, m uniform corss sectional area A and length L is accelerated by applying force F as shown in figure on a smooth surface. If yougs' modulus of elasticity of the material of rod is Y. (Consider x as measured from the right end).

A

Tension in rod as a function of distance x is `(Fx)/(2L)`

B

Strain in rod is `(F)/(2AY)`

C

Elastic potential energy stored in the rod is `(F^(2)L)/(6AY)`

D
