Motion of charged particle in uniform electric field MCQ - Practice Questions with Answers

Motion of a charged particle in a uniform electric field -

Whenever a charged placed in an electric field, it will experience an electric force. Their is an assumption that this whole system is placed in a gravity free space. For this condition, electrical force is the only force acting on the particle. This net force will cause the particle to accelerate according to Newton's second law of motion. So we can write -

${\overrightarrow{F}}_e=q\overrightarrow{E}=m\overrightarrow{a}$

Acceleration will be constant if the Electric field will be uniform and

$\overrightarrow{a}=\frac{q\overrightarrow{E}}{m}$
 The direction of acceleration or motion of a charged particle depends on its

nature. If the charged particle is positive then it will move or accelerate in the direction of electric field. But in case of negatively charged particle its motion or acceleration is in the opposite direction of an electric field. Here we can use the kinematic equation of motion since the acceleration is constant.
