A series of line charges each with constant charge density λ are arranged to create a square with side length s as shown below. (a) Find the electric field a height z above the center of the square. (Hint: consider each side of the square independently, and add all of the electric fields together. ) (b) Suppose s = 1 m, λ = 2.4 μC/m, and z = . 5 m. What is the force on an electron (q = −1.6×10−19 C and m = 9.1×10−31 kg ) placed at this point? What is its acceleration?
