Question

What is the energy of a proton accelerated through a potential difference of 500,000 V?

Answer 1

`8.01\cdot10^(-14)J`

Step-by-step explanation

We want to find the energy of the proton accelerated through the given potential.

To do this, apply the relationship between energy and potential:

`V=(E)/(q)`

where q = charge

V = potential

The charge of a proton is:

`1.602\cdot10^(-19)C`

Therefore, we have that the energy of the proton is:

`\begin{gathered} E=V\cdot q \\ E=500000\cdot1.602\cdot10^(-19) \\ E=8.01\cdot10^(-14)J \end{gathered}`

That is the answer.
