A charged particle is placed in an electric field that varies with location.No force is exerted on this charge: A)at locations where the electric field is zero B)at locations where the electric field strength is 1/(1.6 * 10^-19)N/C C)if the particle is moving along a field line D)if the particle is moving perpendicular to a field line E)if the field is caused by an equal amount of positive and negative charge

Question

Quizplus · Accepted Answer

A charged particle placed in an electric field experiences a force given by F=qE, where q is the charge of the particle and E is the electric field strength. Therefore, if the electric field strength is zero (option A), the particle will not experience any force and will remain stationary. Option B gives a specific value of electric field strength, which may or may not be zero depending on the situation. Option C is incorrect because the particle's motion along a field line does not necessarily mean that it will not experience a force. Option D is also incorrect because if the particle is moving perpendicular to a field line, it will experience a force that is perpendicular to its velocity, resulting in curvilinear motion. Option E is also incorrect because the net effect of a combination of positive and negative charges is the electric field that is produced. If the electric field strength at a point is zero, it means that the net effect of the positive and negative charges cancel each other out at that point.
