inside E o Q ε Φ = = R A ρ )] T T ( 1 [ R R o o - α + = = R A ρ 2 . mag and directions of electric field ½ btwn the 2 charges. (1/2 way btwn is 2m) Add once they point in the same direction. Direction of E. Field is in the negative x direction, because the point charge is + and therefore repulsed by the +7nC charge and attracted to the -5nC charge. If they were the same sign they would subtract as the vectors are pointed in the opposite direction. 3. Gauss’ Law states that the electric flux through any closed surface is equal to the net charge Q inside the surface divided by ε o(can be used to calculate ELECTRIC FIELDS) EA = (Permittivity - material's ability to transmit electric field) What is the ELECTRIC FLUX through the surface? 4. If a battery is connected to parallel plates what is the magnitude of the electric field between the plates. V =-E x Δ Δ E= V/x 5. A charge of is at the origin and a charge of is at the point - Find the electric potential at?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
