An unknown additional charge q3 is now placed at point B, located at coordinates (0 m, 15.0 m ). Find the magnitude and sign of
q3 needed to make the total electric field at point A equal to zero.
1 answer:
The first part of the question is:
Two point charges are placed on the x axis. (Attached file)The first charge, q1 = 8.00 nC , is placed a distance 16.0 m from the origin along the positive x axis; the second charge, q2 = 6.00 nC , is placed a distance 9.00 m from the origin along the negative x axis.
Answer:
q3 = +0.3nc
Explanation:
Due to the vector symbols in the solution, I've decided to attach the explanation to this answer.

Explanation:
The modulus of elasticity (called <em>"alargamiento unitario"</em> in spanish) of a spring is given by the following formula:
Where:
is the original length of the spring
is the elongation of the spring, being
the length of the spring after a force is applied to it.
Then:
