- 1An electrostatic force of attraction between two charged objects occurs when the two charges:have opposite signs (opposites attract)
- 2If the distance between two point charges is increased by a factor of 3, the magnitude of the electrostatic force between them will be changed by what factor?1/9
- 3The electric flux through a closed Gaussian surface that encloses the three charges: q1= -3.0nC , q2= -1.0nC & q3= 5.0nC is:positive
- 4Two POSITIVE charges (q>0) of equal magnitude are placed a distance 'a' on either side of the origin along the horizontal axis, as shown in the figure. What is the direction of the total electric total field at the point P?To the LEFT
- 5Two NEGATIVE charges (q>0) of equal magnitude are placed a distance 'a' on either side of the origin along the horizontal axis, as shown in the figure. What is the direction of the total electric total field at the point P?to the RIGHT
- 6A closed surfaces encloses a positive point charge q. What happens to the total flux through the surface if the VOLUME of the sphere is doubled. (Hint: Use Gauss' Law)?The flux remains the same????
- 7A closed surfaces encloses a positive point charge q. What happens to the total flux through the surface if the MAGNITUDE of the charge is doubled. (Hint: Use Gauss' Law)?The flux is doubled
- 8If a POSITIVE charge is placed in an electric field and released, it will move towards:Lower electric potential energy
- 9If a NEGATIVE charge is released from rest in a constant electric field:its kinetic energy will begin to increase
- 10A fully parallel-plate capacitor remains connected to a battery. If the separation between the capacitor plates is decreased, the potential difference between the plates:Remains the same
- 11If a dielectric with dielectric constant K>1 is inserted between the plates of a capacitor, the capacitance:Increases
- 12A fully charged capacitor is disconnected from the battery. If a dielectric (K>1) is now inserted between the plates, the potential difference across the capacitor:Decreases
