Suppose a Uniform Electric Field of 4 N/C Is in the Positive

question 29

Multiple Choice

Suppose a uniform electric field of 4 N/C is in the positive x direction. When a charge is placed at and fixed to the origin, the resulting electric field on the x axis at x = 2 m becomes zero. What is the magnitude of the electric field at x = 4 m on the x axis at this time?

• A) 0
• B) 1 N/C
• C) 2 N/C
• D) 4 N/C
• E) More information is needed to find the resulting field magnitude at this position.

Definitions:

Null Hypotheses

Hypotheses that state there is no significant difference or relationship between specified populations, any observed difference being due to sampling or experimental error.

Main Effect

The direct influence of an independent variable on a dependent variable in an experiment, ignoring the effects of all other independent variables.

Factorial ANOVA

A statistical method designed to evaluate the impact of two or more variables acting independently at various levels on an outcome variable.

Interaction Effect

Occurs when the effect of one independent variable on the dependent variable changes depending on the level of another independent variable.
