Mexico Mexico language to is the answer to the question
Answer:
-17.5 nC
Explanation:
charge A = -30 nC
charge B = -5 nC
After adding them it would be the average of the two charges because of the getting same voltage difference. so
c = (-30+(-5)) / 2 nC
c= -17.5 nC
answer is -17.5 nC
-- Change the battery to one with higher voltage.
-- Wrap more turns of wire around the spike.
-- If the spike is made of anything else but iron, replace it with a pure iron one.
Answer:
i E=V/d=50/2*10^-3=25*10^3 N/C
ii It is a (+) and (-)
iii C=εA/d
C=12.56*10^-8 * 0.1/2*10^-4
C=62.83 μF
Q=CV=50*6.283*10^-6
Q=314 μC
iv E=0.5 QV
=0.5(50*314*10^-6)
=7850 μJoule
