determine the center of mass of a rod, considering that the linear density varies from λ = λ0 at x = 0 the left end to double that value at the right end λ = 2 λ0 at x = L.
where λ is the charge density per unit length on the rod and εο is called the permittivity of free space (it is a universal constant with the value 8.854 x 10-12 F/m (farads per metre)) The integral for the electric field can be evaluated exactly using a method called trigonometric substitution with the result AL We won't learn the method of trigonometric substitution in this course; however, you will approximate the value of the integral using methods we introduced...
