Electronic types neglect the force of gravity on
Chapter 14, Problem 4P(choose chapter or problem)
Electronic types neglect the force of gravity on electrons. To see why, compute the force of Earth’s gravity on an electron and compare it with the force exerted on the electron by an electric field of magnitude 10,000 V/m (a relatively small field). The mass and charge of an electron are given on the inside back cover.

QUESTION:
Electronic types neglect the force of gravity on electrons. To see why, compute the force of Earth’s gravity on an electron and compare it with the force exerted on the electron by an electric field of magnitude 10,000 V/m (a relatively small field). The mass and charge of an electron are given on the inside back cover.
ANSWER:Solution 4P 31 The mass of an electron is = 9.1 × 10 kg 31 2 The weight of an electron is = 9.1 × 10 kg × 9.8 m/s = 89.18 × 10 31N The charge of an electron is = 1.6 × 1019C The ma
