A uniform line charge extends from x = - 2.7 cm to x = + 2.7 cm and has a linear charge density of = 5.9 nC/m.
(a) Find the total charge. Find the electric field on the y axis at the following distances.
(b) y = 4 cm
(c) y = 12 cm N]
(d) y = 4.5 m
(e) Find the field at y = 4.5 m, assuming the charge to be a point charge.
