## Question:

Electric charge is non relativistic. Explain.

## Relativity and Relativistic

Relativity is the branch of Physics, which deals with the objects which travel at a speed comparable to the speed of light. Relativistic quantities are those quantities that vary with the speed for example mass increases with speed, or length decreases with speed.

Electric charge is non-relativistic.

Relativistic quantities are those quantities that vary with the speed for example mass, length or time. The mass of an object at rest is different from the mass of an object in motion

{eq}\begin{align} m = \frac{m_0}{\sqrt{1-\frac{v^2}{c^2}}} \end{align} {/eq}

where m is the moss in motion, v is the speed of the object, c is the speed of light, and {eq}m_0 {/eq} is the mass of the object at rest.

Now we talk about the charge, the charge on an electron remains the same irrespective of the fact whether the electron is at rest or in motion or irrespective of the speed of the electron charge remains the same.

So the charge is non-relativistic.
