Answer:
A) E = 3.70*10^{4} N/C
B) E = 2.281*10^3 N/C
Explanation:
given data:
charge density
length of wire = 9.50 cm
a) at x = 4.5 m above midpoint, electric field is calculated as
x = 4.5 cm
midpoint a = 4.5 cm = 0.0475 m
E = 3.70*10^{4} N/C
B) when wire is in circle form
= 1.235*10^{-8} C
Radius of circle
r = 1.511*10^{-2} m
E = 2.281*10^3 N/C
Because they perform different functions

A. is a neutral substance.
Only neutral substances (like pure water) can have a pH of 7.
It goes faster or slower because there is more space inbetween
