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
In uniform E, F = qE = ma, so a = qE/m is constant. For +q, a ∥ E; for –q, a ∝ –E. Statement iv is meaningless.
Hint
F = qE, constant E → constant a.
