Physics (Electric fields and Coulomb's Law)
posted by Kathy on .
I need help with this question please.
An ion harvester is scouring deep space for isolated xenon (Xe+) ions. A xenon ion is singly ionized, and has a charge of +e. If the field meter reads 0.000000202 N/C, how far away is it from the ion?
E = kQ/R^2 = 202*10^-9 N/C
Q = +e = 1.6*10^-19 C
k is the Coulomb constant
Solve for R
