`CDEF` is a fixed conducting smooth frame in vertical plane. A conducting uniform rod `GH` of mass `m` can move vertically and smoothly without losing contact with the frame. `Gh` always remains horizontal and is given velocity `u` upward and released. Taking the acceleration due to gravity as `g` and present other than `R`. Find out the time tasken by the rod to reach the highest point.
