Question
In evaluating the integral in Gauss’ law for a spherical surface centered on a negatively charged particle, which describes the dot product of the electric field and a differential area vector?a) The dot product is positive because the vectors are in the same direction.
b) The dot product is negative because the vectors are in opposite directions.
c) The dot product is negative because the vectors are in the same direction.
d) The dot product is positive because the vectors are in opposite directions.
Explanation / Answer
The dot product is negative because the vectors are in opposite directions.
