Question
Which is/are correct about the acceleration experienced by a charged particle in a uniform electric field? i. for a uniform field, acceleration is constant; ii. For a positively charged particle, the acceleration is in the direction of the field; iii. For a negatively charged particle, the acceleration is opposite direction of the field; iv. radially outward if the field is negative.
Correct Answer
Option D is the correct answer.
Detailed Explanation
Uniform field implies constant force (F=qE) and thus constant acceleration (a=F/m). Positives move with field, negatives move against
Hint
Force direction depends on the charge's sign in an electric field.
