Question

Badri makes the table below to review the factors that affect the electric force between objects.

A 2-column table with 2 rows. The first column labeled Factor has entries Distance, Mass. The second column labeled Relationship to Strength of Electric Force has entries Indirect, Direct.
Which change will correct the error in Badri’s table?

changing “Direct” to “Indirect”
changing “Indirect” to “Direct”
changing “Distance” to “Amount of electric charge”
changing “Mass” to “Amount of electric charge”

Answer 1

changing “Mass” to “Amount of electric charge”

Explanation: electric force depends directly on the magnitudes of the charges and inversely on the distance squared; it does not depend on mass.
