One giga electron volt (1 Gev) is equal to

Options

A. `10^(8)` eV
B. `10^(9)` eV
C. `10^(10)`eV
D. `10^(12)` eV

Answer

To solve the question "One giga electron volt (1 GeV) is equal to what?", we can follow these steps:

### Step 1: Understand the Prefix "Giga"
The term "giga" is a metric prefix that denotes a factor of \(10^9\). This means that 1 giga is equal to \(10^9\).

### Step 2: Define Electron Volt
An electron volt (eV) is a unit of energy that is commonly used in the field of particle physics. It is defined as the amount of kinetic energy gained by a single electron when it is accelerated through an electric potential difference of one volt.

### Step 3: Convert Giga Electron Volt to Electron Volt
Since 1 GeV is equal to \(10^9\) eV, we can express this mathematically:
\[ 1 \text{ GeV} = 1 \times 10^9 \text{ eV} \]

### Step 4: Final Answer
Thus, we conclude that:
\[ 1 \text{ GeV} = 10^9 \text{ eV} \]

### Summary
The answer to the question "One giga electron volt (1 GeV) is equal to" is:
\[ 10^9 \text{ electron volts (eV)} \]
