Short Answer

How are units of volts and electron volts related? How do they differ?

They are related by the given expression-

1 eV = (1.60 x 10-19 C) (1V)

The main difference is that Volt is the unit of potential difference whereas electron-volts is the unit of energy.

Step by Step Solution

TABLE OF CONTENTS

Step 1: Definition of Electron Volts

The amount of kinetic energy gained by a single electron accelerating from rest for one-volt electric potential difference in vacuum is measured in electron-volts.

Step 2 : Explaning the relationship between volts and electron volts

The relation between volts and electron-volts is given as-

1 eV = (1.60 x 10-19 C) (1V)

Thus, electron-volts is defined as the amount of work done in carrying an electron between two points having a potential difference of 1V between them.

The main difference between them is that the electron-volts is a unit of energy, whereas the volt is the unit of electric potential difference.

In one of the classic nuclear physics experiments at the beginning of the \(20{\rm{ }}th\) century, an alpha particle was accelerated toward a gold nucleus, and its path was substantially deflected by the Coulomb interaction. If the energy of the doubly charged alpha nucleus was \(5.00{\rm{ }}MeV\), how close to the gold nucleus (\(79\) protons) could it come before being deflected?

In what region of space is the potential due to a uniformly charged sphere the same as that of a point charge? In what region does it differ from that of a point charge?

Does the capacitance of a device depend on the applied voltage? What about the charge stored in it?

What are the sign and magnitude of a point charge that produces a potential of \(-2.00{\rm{ }}V\) at a distance of \(1.00{\rm{ mm}}\)?

The naturally occurring charge on the ground on a fine day out in the open country is \( - 1.00n{\rm{ }}C/{m^2}\).
