lculate the speed of an elec

A parallel-plate capacitor is charged to an electric potential of 347 V by moving 3.60E+16 electrons from one plate to the other. How much work is done in charging the capacitor?

In a television picture tube, electrons strike the screen after being accelerated from rest through a potential difference of 17000 V. The speeds of the electrons are quite large, and for accurate calculations of the speeds, the effects of special relativity must be taken into account. Ignoring such effects, find the electron speed just before the electron strikes the screen.

An electron is accelerated from rest through a potential difference of 181 V. What is the electron's final speed? (e = 1.60×10-¹9 C, Melectron 9.11x10-31 kg) =

Two charged plates are used to accelerate an electron in an old tube television.  If the potential is 499 V, what is the speed of the electron as it leaves, in m/s?

A proton with a charge of 1.60 × 10-¹9 C is shot from plate B toward plate A with a speed of 1.5 × 106 m/s. (= 1.0 × 10* V/m, d = 0.0030 m) Draw a picture of situation. (a) What is the electric potential between the plates? (b) What will the speed of the proton be just before it hits plate A?

If an electron is accelerated from rest through a potential difference of 1200 V, find its approximate velocity at the end of this process. (e=16x 10-19 Cm,-9.1 x 10-31 kg) ⒸLOX 107m's 14 x 10m's 21x107m's O 25 x 107 m/s MacBook Air

3. How much work must we do on an electron to move it from point A, which is at a potential of +50V, to point B, which is at a potential of -50 V, along the semicircular path shown in the figure? Assume the system is isolated from outside forces. A) 1.6 J B) 1.60 × 10-17 J C) -1.60 × 10-17 J D) -1.6 J A +50V B - 50 V

An electron moves through an electric field, and its speed drops from 2,500 m/s to 1,000 m/s. What's the potential difference between the two points at which the speed was measured Give the potential difference if the initial and final speeds are 2370 and 1020 m/s
