Question
In Coulomb's law, two positive charges_each other repel attract no force In defining an electric field, a test charge is used. Is the test charge positively or negatively charged? Which describes the direction of the electric field vector? Negatively charged. The field vector is in the same direction as the force on the test charge. Positively charged. The field vector is in the same direction as the force on the test charge. Positively charged. The field is in the opposite direction from the force on the test charge. Which describes the electric flux through a section of a closed surface? It is a vector that is directed outward through the section. It is a vector that is tangent to the section. It is a scalar. Three capacitors, each of capacitance C are connected to a battery. What is C_eq of the three capacitors if they are connected to a battery in series with one another? C 3C C/3 In the figure, two particles of charge -q are arranged symmetrically about the y axis; each produces an electric field at point P on that axis. Are the magnitudes of the fields at P equal?Explanation / Answer
4) two like charges repel each other
5) B) positiveky charged . the field is in the same direction as the force on the charge
6) Option A
7) Capacitance in series = C+ C+C = 3C
so option B is the correct answer
8) Ef at P = 2 ( kq / (2d^2) * 1/sqrt 2)
= kq / sqrt 2 d^2
