Dear pallavi

consider a small length dx at adistance x on the rod from the axis of rotation

mass of liquid in dx legth = dm = M/L dx

centrifugal force is acting  on dm mass

 dF = dm x ω2

 F = ∫df  =∫dm x ω2

             =M/L ω2∫x dx        limit 0 to L


this force is balance by normal reaction on fluid by other end

N =   MLω2/2
