If an electron has an initial velocity in a direction different from that of an electric field, the path of the electron is

Options

  1. Aa straight line
  2. Ba circle
  3. Can ellipse
  4. Da parabola

Correct answer

D. a parabola

Step-by-step solution

The path is a parabola, because initial velocity can be resolved into two rectangular components, one along E→\overrightarrow{\mathrm{E}} and other ⊥\perp to E→\overrightarrow{\mathrm{E}}. The former decreases at a constant rate and latter is unaffected. The resultant path is therefore a parabola.
