Question

Step 3: Enter your full question details here
f (electric flux) = EdA = Q/e,   ?=-90.0µC/m Solution says EA= ?l/e, E2prl=?l/e, E=?/2pre (next to last step), E=2?/4pre (last step). Please explain how got from next to last step to last step. Where do the 2 in the numerator and the 4 in the denominator come from. Step 3: Enter your full question details here

Explanation / Answer

E = ?/2pre to E = 2?/4pre delibrately multiply by 2 on both up and bottom sides in order to use 1/4pe = 9*10^9
