PHY 102 Last Minute Prep Objective Question

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.
Options
A i only
B ii only
C iii only
D i, ii & iii
Correct Answer
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.
