A uniform electric field E exists between the plates of a charged condenser. A charged particle enters the space between the plates and perpendicular to E . The path of the particle between the plates is a:

Options

  1. Astraight line
  2. Bhyperbola
  3. Cparabola
  4. Dcircle

Correct answer

C. parabola

Step-by-step solution

When charged particle enters perpendicularly in an electric field, it describes a parabolic path y = 1 2 ( QE m ) ( x 4 )^2 This is the equation of parabola.
