I also feel answer is B
let the mass/unit length =  =M/L
v = [2] T/ = = [2]gx/ = [2] gx

All that is gold does not glitter
Not all who wander are lost
The old that is strong does not wither,
Deep roots are not reached by frost.
From ashes a fire shall be woken
From shadows a light shall spring
Renewed shall be blade that's broken
The crown less again shall be king. |
