An air-filled capacitor is connected to a 9V battery. The air in the capacitor is carefully replaced with mineral oil while the capacitor remains connected to the battery. Consequently, we can expect this to happen. O a. The electric field E between the plates will become stronger. O b. The charge Q accumulated in the capacitor will remain the same. c. The electric flux density D in the capacitor will become weaker. O d. The electric flux density D between the plates will become stronger.

2. Suppose that charge #1 is positioned at the origin (x = 0 m, y = 0 m) and has a magnitude of +2.6 μC, and that charge #2 is positioned on the y-axis at y = 0.16 m and has a magnitude of -4.3 µC. Find the x- and y-components of the electric field on the x-axis at x = 0.21 m. Also, find the x- and y-components of the force on a charge of +6.3 nC placed at this point (x = 0.21 m).
