#### Answer

No, there is no upper limit to the electron’s momentum.

#### Work Step by Step

The relativistic momentum of the electron is given by equation 26-4. At low speeds (relative to c), this is basically the same as p=mv. As v approaches c, the value of $\gamma = \frac{1}{\sqrt{1-v^{2}/c^{2}}}$ approaches infinity.
