Question

A uniform line charge that has a linear charge density λ = 4.1 nC/m is on the x axis between x = 0 to x-5.0 m (a) what is its total charge? (b) Find the electric field on the x axis at x = 6 m 1 23e 10 × N/C ci the electric field on the x axis at x 8.0 m N/C (d) Find the electric field on the x axis at x 300 m N/C (e)Estimate the electric field at x 300 m, using the approximation that the charge is a point charge on the x axis at x - 2.5 m. N/C () Cormpare your result with the result calculated in part (d) by finding the ratio of the approximation to the exact result. To do this, you will need to assume that the values given in this problern statement are valld to more than two significant figures (9) Is your approximate result greater or smaller than the exact result? O greater O smaller

Answer 1

Concept used:- here we use the result for field due to a charged rod for calculation, and the concept of linear distribution of charge,
