Homework Statement
Pls help me with the (d) option of the question asked in the link
https://www.physicsforums.com/showthread.php?t=724332&page=1
Correct expression for tension is ρgx/6 (as given in the answer sheet)
Homework Equations
The Attempt at a Solution
Velocity as a function of x is ##\sqrt{\frac{2gx}{3}}## (acc. to the solution of previous post)
[itex]\Rightarrow[/itex] a = [itex]dv/dt[/itex] = [itex]g/3[/itex]
applying Newton's law
ρg[itex]x/2[/itex] - T = ρ[itex]g/3[/itex]*[itex]x/2[/itex]
[itex]\Rightarrow[/itex] T = ρg[itex]x/3[/itex]
Pls help me to find the correct answer.
