A proton (m = 1.67 x 10-27 kg) travels a distance of 3.2 cm parallel to a uniform electric field 3.4 x105 V/m between the plates shown in the figure. If the initial velocity is 1.5 x 105 m/s, find the magnitude of its final velocity in m/s. (* Ignore gravity) Round your answer to 0 decimal places.

How do I rearrange this equation so that I am solving for t?

QUESTION 4 An electron is released from rest at the negative plate of a parallel plate capacitor and accelerates to the positive plate. The plates are separated by a distance of 1.39 cm, and the electric field within the capacitor has a magnitude of 1743307 V/m. What is the kinetic energy of the electron just as it reaches the positive plate? (Give your answer in 2 d.p. with scientific notation(i.e. 1.23e-12)} 1 Electric field Electron F + + + + + + + + + +

The voltage is constant inside the circular electrodes. What does that mean for the electric field inside the electrode. (the electric field inside a conductor is zero!). Draw arrows from the dots within this electric field to show what would happen?

A cathode-ray tube accelerates electrons to a speed of 26500 kms−1V. What is the potential difference across the tube?

1. The magnitude of an electric field became 3.0 x 106 N/C or greater, so that electrical breakdown and thus sparking could occur. 2. The energy of a spark was 150 mJ or greater so that it could ignite the powder explosively. Let us check for the first condition in the powder flow through the plastic pipes. Suppose a stream of negatively charged powder was blown through a cylindrical pipe of radius R = 5.0 cm. Assume that the powder and its charge were spread uniformly through the pipe with a volume charge density p. a. Using Gauss' law, find an expression for the magnitude of the electric field E in the pipe as a function of radial distance r from the pipe center. b. Does E increase or decrease with increasing r? c. Is E directed radially inward or outward? d. For p = 1.1 x 10³ C/m³ (a typical value at the factory), find the maximum E and determine where that maximum field occurs. e. Could sparking occur, and if so, where? From the answer to part (a) of the problem, f. Find an…

eV is a unit used in nuclear physics for the energy of particles. If an electron's charge is 1.6 * 10^-19 C, and its mass is 9.1 * 10^-31 kg, what is the speed of an electron with 1 eV kinetic energy to one significant figure? A) 600000 m/s (B) 5000000000 m/s (C) 2200 m/s D) 40000 m/s
