Explanation:
From the question we are told that
The mass of the rod is 
The distance of separation is 
The current is
The coefficient of friction is 
Generally for the rod the rod to continue moving at a constant speed
The frictional force must equal to the magnetic field force so

Where 
and 

=> 
substituting values
