A thin conducting square plate 1.0 m on the side is given a charge of −2.0 ✕ 10−6 C. An electron is placed 1.0 cm above the center of the plate. What is the acceleration of the electron? (Enter the magnitude in m/s2.)

Which of the following changes will increase the capacitance of a parallel-plate capacitor? (there could be more than one correct choice.) a) increase the charge on the plates b) decrease the poten5al between the plates c) increase the potential between the plates d) introduce a dielectric material between the plates e) decrease the separation between the plates
