An experimental device uses electrical energy to accelerate a projectile motion. Using dimensional analysis alone, what can you determine about how the accelerating force, F, depends on the current, I, if the only other quantities which need to be considered are the thickness of the rails, d, the distance between the rails,D, and the constant known as the permeability of free space, µo. 2 The value of uo is 47 × 10-7 N/A², so [µo] = .
