PHY 102 ELECTROSTATICS Objective Question

Question

If a charge is launched at a right angle to a uniform electric field, the document states that it moves on a _________ until it hits the plate to which it is directed.
Options
A Straight line.
B Circular path.
C Parabola.
Correct Answer
D Helical path.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 19, under 'The Electric Field between two Parallel Oppositely Charged Sheets', states: 'If you launch a charge at right angle to the field, it experiences a constant force which is perpendicular to its motion. This is like the situation with a projectile launched horizontally. ... The charge moves on a parabola until it hits the plate to which it is directed.'

Hint

Consider the analogy given in the text about projectile motion under gravity.
