Magnetic Effects Of Current Question 372
Electric charge q is uniformly distributed over a rod of length ℓ. The rod is placed parallel to a long wire carrying a current i. The separation between the rod and the wire is a. Find the force needed to move the rod along its length with a uniform velocity v. If it is $ \frac{{\mu_{0}}i}{2\pi a}\times xN $ . Find x. $ (q=2C,V=2m/s,a=1m) $
