1. ### Capacitors & Dielectrics

got it! Thanks a lot!
2. ### Capacitors & Dielectrics

Homework Statement Two capacitors are identical, except that one is empty and the other is filled with a dielectric (κ = 3.20). The empty capacitor is connected to a 11.0-V battery. What must be the potential difference across the plates of the capacitor filled with a dielectric such that it...
3. ### Two Charges, Find Spot of Zero Potential

Homework Statement Charges of -q and +2q are fixed in place, with a distance d = 6.00 m between them. A dashed line is drawn through the negative charge, perpendicular to the line between the charges. On the dashed line, at a distance L from the negative charge, there is at least one spot...
4. ### Electrical Forces, Torque & Flux

Homework Statement A long, thin rod (length = 4.0 m) lies along the x axis, with its midpoint at the origin. In a vacuum, a +6.0 C point charge is fixed to one end of the rod, and a -6.0 C point charge is fixed to the other end. Everywhere in the x, y plane there is a constant external...
5. ### Net Force of Point Charges, Coulomb's law

Thanks! I got it right, and because I changed my calculator back to degrees I also was able to figure out why another problem wasn't working - Thanks for your help!
6. ### Coulomb's Law & Electrons

Thanks for your help, It's good to know I'm not crazy hah
7. ### Net Force of Point Charges, Coulomb's law

Homework Statement The drawing shows three point charges fixed in place. The charge at the coordinate origin has a value of q1 = +8.02 C; the other two have identical magnitudes, but opposite signs: q2 = -4.73 C and q3 = +4.73 C. (a) Determine the net force exerted on q1 by the other two...
8. ### Coulomb's Law & Electrons

Homework Statement Two spherical objects are separated by a distance of 1.98 x 10-3 m. The objects are initially electrically neutral and are very small compared to the distance between them. Each object acquires the same negative charge due to the addition of electrons. As a result, each...
