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 and other perpendicular to E . The former decreases at a constant rate and later is unaffected. The resultant path is, therefore a parabola.
