The figure shows the path of a positively charged particle `1` through a rectangualr region of unifrom electric field as shown in the figure. What is the direction of electric field and the direction of deflection of particles `2, 3` and `4` ?

Options

A. Top, down, top, down
B. Top, down, down, top
C. Down, top, top, down
D. Diwn, top, down, down

Answer

A

Explanation

The figure shows the parth of `+ve` charged particle `(1)` through a rectangualr region of unifrom electirc field.

Since, `+ve` charged particel moves as a parabolic path in electric field, it means the direction of electric field is upward. the direction of deflection of particle `(2)` which is `-ve` is downward.
The direction of deflection of particle `(3)` which is `+ve` is upward and direction of particle `(4)` is downward.
