In a certain region of space electric field \(\vec{E}\) and magnetic field \(\text { E }\) are perpendicular to each other and an electron enters in region perpendiculars to the direction of \(\overrightarrow{\mathrm{E}} \text { and } \overrightarrow{\mathrm{E}}\) both and moves undeflected, then velocity of electron is:
- \(\frac{|\vec{E}|}{|\vec{E}|}\)
- \(\vec{E} \times \vec{E}\)
- \(\frac{|\overrightarrow{\mathrm{E}}|}{|\overrightarrow{\mathrm{E}}|}\)
- \(\vec{E} \cdot \vec{E}\)
Answer
(C) | E | | E |
