1. How is the attractive electrostatic force between a proton and an electron indicated in Coulomb's law?
the sum of the charges indicates a positive force
the product of the charges indicates a positive force
the product of the charges indicates a negative force
the sum of the charges indicates a negative force
2. One particle has a negative charge, while another particle is neutral. Which statement describes the electrostatic force between these two particles?
There would be no electrostatic force because the sum of the two charges is 0.
The electrostatic force is attractive due to the particle with negative charge.
There would be no electrostatic force because the product of the two charges is 0.
The electrostatic force is repulsive due to the particle with negative charge.
3. How would the electrostatic force change if Coulomb's law included a negative sign?
Like charges would repel, and opposite charges would attract.
It would not make a difference in the electrostatic force.
It would depend on the magnitude of the charges.
Like charges would attract, and opposite charges would repel.
What is the value and the direction of an electric field at a distance of 2.5 m from a +1 nC charge?
approximately 145 V/m directed away from the positive charge
approximately 145 V/m directed toward the positive charge
approximately 1.45 V/m directed away from the positive charge
approximately 1.45 V/m directed toward the positive charge
