Two large parallel plates carry opposite charges of equal magnitude. They are separated by 80.0 mm and the potential difference is 120 V. What is a magnitude of the uniform electric field in the region between the plates?

Two 1.7-cm-diameter disks face each other, 1.5 mm apart. They are charged to ± 10 nC. What is the electric field strength between the disks? A proton is shot from the negative disk toward the positive disk. What launch speed must the proton have to just barely reach the positive disk?

A proton with a kinetic energy of 1.63 keV (1eV-1.602.10-19 J), that is at height 24.9 cm above a horizontal charged nonconducting plate with surface charge density - 3.60 μ C/m², is fired horizontally across this plate. What is the height of the proton after it has traveled a horizontal distance of 3.56 cm? 18.6 cm O 13.8 cm O 20.9 cm O 15.4 cm O 20.2 cm Save for Later Submit Answer

A constant electric field of 20.0 N/C points along the positive x-direction. An electron, initially at rest, moves a distance of 0.500 m in this space. How fast is the electron moving after its 0.500 m journey?

Two parallel, flat, conducting plates with equal but opposite charges are separated by a uniform layer of insulating material with a dielectric constant of 7.1 and a thickness of 1.7mmmm. The electric field in the dielectric material is 2.22MV/mMV/m. What is the magnitude, in microcoulombs per squared meter, of the surface charge density on the conducting plates? What is the magnitude, in microcoulombs per squared meter, of the surface charge density on the conducting plates?

A parallel-plate capacitor is formed from two 5.8 cm -diameter electrodes spaced 1.9 mm apart. The electric field strength inside the capacitor is 1.0 ×106N/C. What is the charge (in nC) on each electrode?

Two large parallel copper plates are 7.39 cm apart and have a uniform electric field of magnitude E = 3.44 N/C between them (see the figure). An electron is released from the negative plate at the same time that a proton is released from the positive plate. Neglect the force of the particles on each other and find their distance from the positive plate when they pass each other. Positive Negative plate plate P E Number i Units

A small drop of water is suspended motionless in air by a uniform electric field that is directed upward and has a magnitude of 7420 N/C. The mass of the water drop is 4.78 × 10-9 kg. How many excess electrons or protons reside on the drop

The drawing shows an electron entering the lower left side of a parallel plate capacitor and exiting at the upper right side. The initial speed of the electron is 3.13 × 106 m/s. The capacitor is 2.00 cm long, and its plates are separated by 0.150 cm. Assume that the electric field between the plates is uniform everywhere and find its magnitude. 15.30 + A + 2.00 cm Number i + + + 0.150 cm Units
