A sheet of mica is inserted between the plates of an isolated charged parallel-plate capaci- tor. Mica is a transparent mineral that comes naturally in thin sheets, and is an excellent dielectric. Which of the following statements is true? 1. The capacitance decreases. 2. The charge on the capacitor plates de- creases. 3. The electric field between the capacitor plates increases. 4. The energy of the capacitor does not change. 5. The potential difference across the capac- itor decreases 015 10.0 points In order to store more energy in a parallel- plate capacitor whose plates differ by a fixed voltage. what change would you make in the plates?

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
