In the figure, `CDEF` is a fixed conducting smooth frame in vertical plane.A conducting uniform rod `GH` of mass `m=1 g` can move vertically and smoothly without losing contact with the frame.`GH` always remains horizontal.It is given velocity `u=1m//s` upwards and released.Taking the acceleration due to gravity as `g` and assuming that no resistance is present other than `R`.Time taken by rod to reach the highest point is equal to `(ln10)/x` second.Find out value of `x`.
