A uniform electric field `vecE` exists between the plates of a charged condenser. A charged particle enters the space between the plates and perpendiculars to `vecE`. The path of the particle between the plates is a

Options

A. Straight line
B. hyperbola
C. parabola
D. circle

Answer

C

Explanation

When charged particle eneters perpendicularly in an electric field, it describes a parabolic path
`y=1/2((QE)/m)(x/4)^(2)`

This is the equation of parabola.
