(a) What is the total charge? (b) Find the electric field on the x axis at x = 6

Question

(a) What is the total charge?

(b) Find the electric field on the x axis at x = 6 m.

(c) Find the electric field on the x axis at x = 11 m.

(d) Find the electric field on the x axis at x = 290 m.

(e) Find the field at x = 290 m, using the approximation that the charge is a point charge at the origin.

Compare your result with that for the exact calculation in part (d)

A uniform line charge of linear charge density = 4.3 nC/m extends from x = 0 to x = 5 m What is the total charge? Find the electric field on the x axis at x = 6 m. Find the electric field on the x axis at x = 11 m. Find the electric field on the x axis at x = 290 m. Find the field at x = 290 m, using the approximation that the charge is a point charge at the origin. Compare your result with that for the exact calculation in part (d)

Explanation / Answer

a)total charge=4.3*5=21.5 nC

b)Electric field at x=6 m is 32.25 N/m

c)at x=11 m electric field is 17.59 N/m

d)at x=290 m electric field is 0.6672 N/m

e)assuming point charge then electric filed at x=290 m is .0023 N/c
