Question 1.
What is the unit of electric field?
Show hintHide hint
Think about the force experienced per unit charge.
Question 2.
Define field lines in the context of electric fields.
Show hintHide hint
How do these lines represent forces?
3Question 3.
What is the electric field due to a point charge?
- E = F/q
- E = q/r^2
- E = k*q/r^2
Show hintHide hint
Think about the role of Coulomb's Law.
4Question 4.
True or False: Electric field lines can intersect.
- True
- False
Show hintHide hint
What would it mean for two lines to cross?
Question 5.
Determine the electric field at a point 3 meters away from a 6 μC charge. Use k = 8.99 × 10^9 N m²/C².
Show hintHide hint
Make sure to square the distance appropriately!
Question 6.
Two charges, +5 µC and -5 µC, are 2 m apart. Calculate the electric field at the midpoint, considering both directions.
Show hintHide hint
Consider the directions of the field from each charge!
