Im confused what pC stands for and um
Question: What is the electric field strength 5.0um from a charge of 22pC?
Formula should be= kq/r² N/C
So what do I do next

Ok :
You have distance : 5 um = 5*10^-6 meters
charge = 22pc = 22 pico coulombs = 22*10^-12 C
K = electrostac constant = 9*10^9
E = 9*10^9*22*10-12 / (5*10^-6)^2
E = 198*10^-3 / 25*10^-12
E = 7.92*10^9 (N/C)
Hope that helps

electric container E= - dV /dr As ability is continuous dV / dr =0 as a result electric container is 0 in a area the place electric ability is continuous. as an occasion, interior a hollow charged matallic sphere, the electrical powered container IS 0 however the means interior is continuous and equivalent to ability on the suface of charged sphere

um is micrometers 1um = 10^-6 m
pC is picocoulombs 1pC = 10^-12 C
using coulombs law r = 5*10^-6m and q = 22*10^-12 C, then just plug and chug.

pC is probably PICO (10^-12) coulomb
um is likely be a MICRO (10^-6) meter
