Question

The path of a charged particle entering perpendicularly in a uniform electric field will be:

• A. linear
• B. parabolic
• C. circular
• D. elliptical

Answer 1

Answer: (B)

The equation of motion of the charge entering perpendicular to the electric field is
$y=\frac{qE}{2m{v}^2}{x}^2$
$y\propto x^2$
Therefore, path of a charged particle entering perpendicularly in electric field is parabolic in shape.
