A uniform electric field exists in a region between two oppositely charged plates. An electron is released from rest at the surface of the negatively charged plate and strikes the surface of the opposite plate, 6.0 cm away, in a time 1.6 ✕ 10−8 s. (a) What is the speed of the electron as it strikes the second plate?       __________m/s(b) What is the magnitude of the electric field?        ___________N/C

On a typical clear day, the atmospheric electric field points downward and has a magnitude of approximately 110 N/C. Compare the gravitational and electric forces on a small dust particle of mass 3,1 x 10 g that carries a single electron charge. 1.1134 What is the acceleration (both magnitude and direction) of the dust particle? (Enter the magnitude in m/s.) magnitude m/s direction downward v

One type of ink-jet printer, called an electrostatic ink-jet printer, forms the letters by using deflecting electrodes to steer charged ink drops up and down vertically as the ink jet sweeps horizontally across the page. The ink jet forms 35.0 μm-diameter drops of ink, charges them by spraying 800,000 electrons on the surface, and shoots them toward the page with a horizontal velocity of 17.0 m/s. Along the way, the drops pass through the long axis of two horizontal, parallel electrodes that are 6.0 mm long, 4.0 mm wide, and spaced 1.0 mm apart. The distance from the center of the electrodes to the paper is 1.90 cm. To form the letters, which have a maximum height of 6.0 mm, the drops need to be deflected up or down a maximum of 3.0 mm. Ink, which consists of dye particles suspended in alcohol, has a density of 800 kg/m³. 3 E D 80 C $ 4 R 888 F4 F V % 5 FS T ^ G 6 B Part A What electric field strength is needed between the electrodes to achieve this deflection?

Help me answer this question please. An electron is projected horizontally at a speed of 2.5 x 10*6 m/s between two plates. metal parallel I = 7.5 cm in length as shown in the figure below. The greatness of electric field is 130 N/C. Determined : a) Acceleration of the electron b) The time it takes to escape from the metal plates c) The final vector velocity of the electron as it escapes from the plates

An electron is immersed in a uniform electric field ?⃗ = ???̂. What is the direction of the acceleration of the electron if it has an initial velocity ?⃗ ? = ???̂?

A proton is projected in the positive x direction into a region of uniform electric field E = (-6.20 × 105) ↑ N/C at t = 0. The proton travels 7.90 cm as it comes to rest. (a) Determine the acceleration of the proton. m/s² magnitude direction -X (b) Determine the initial speed of the proton. m/s magnitude direction +X ✓ ✓ (c) Determine the time interval over which the proton comes to rest.

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
