In the figure, 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. It is given velocity ‘u’ upwards and released. Taking the acceleration due to gravity as ‘g’ and assuming that no resistance is present other than ‘R’. Find out time taken by rod to reach the highest point

We know that ;
Power p= (B^2*l^2*v^2/R );
Here R is the resistance, v is the velocity of the rod,and B is the magnetic field of the rod
Hence solve it u will get the answer
