6 Questions
Which particle has the highest charge to mass ratio?
Electron
What is the flux of a uniform electric field through a square of 10 cm on a side parallel to the yz plane?
300 Nm²/C
What is the flux through a square when the normal to its plane makes a 60° angle with the x-axis?
150 Nm²/C
What is the net flux of the uniform electric field through a cube of side 20 cm oriented parallel to the coordinate planes?
0
What is the net charge inside a black box if the net outward flux through its surface is 8.0 × 10³ Nm²/C?
8.0 µC
If the net outward flux through the surface of the box were zero, could you conclude that there were no charges inside the box? Why or why not?
No, charges could still be present inside the box.
Learn about how the magnitude of electric field at a point decreases inversely as the square of the distance from the charge and how field lines represent the direction of the electric field. Explore the concept through Figure 1.12 and understand the relationship between electric field and force on a unit positive charge.
