Chopter 22, Problem 024 Your answer is partially correct. Try again. A thin nonconducting rod with a un rom distribution of positive charge Q IS bent into ? ?rde c radius sec c figure he central perpendicular a 1s through the nng is ? z axis, with the origin at the center o rod at (a) z-0 and (b)2-ao? (c) in terms of R, at what positive value cfz is that magnitude maximum? (d) if R-2.34 cm and Q-4.02 ?·what is the maximum magnitude he ring. What is e magnitude of the electric field due to the (a) Nu (b) N (c) Number 10.707 (d) Numbe5,69379019 Units No units N'C or Vim

Explanation / Answer

b.

Electric field given as

E= KQZ/(Z^2+ R^2)^(3/2)

If z>> R

Then R^2 can be neglected.

E inversely proportional to z^2

Is z= infinity

E= 0 N/C or V/m

-----------

D.

E= 9*10^9* 4.02*10^-6* (0.707)* 2.34*10^-2/( (0.707* 2.34*10^-2)^2+ (2.34*10^-2)^2)^(3/2)

E= 2.543*10^7 N/C or V/m

Comment in case any doubt..goodluck
