The electric field strength 5 cm from a very long charged wire is 2000N/C . What is the field strength 10 cm from wire.
A)1x10^-4 N/C
B)1x10^3 N/C
C)9.9x10^7 N/C
D) None of these
I have
E=kq/r^2 and infinite line charge E=(2k[tex]\lambda[/tex])/R
2000 * .05 m^2 /K =q
q=5.56 E-8
k5.56E-8/.^21 m = 500 N/C so my answer would be D
But its wrong so where am I off? Thanks for the help
