Question 1.
Define electric potential in your own words.
Show hintHide hint
Think of it as energy required to move a charge.
Question 2.
What is the formula for calculating electric potential?
Show hintHide hint
Recall the role of vacuum permittivity in the formula.
3Question 3.
What does electric potential measure?
- Work done per unit mass
- Work done per unit charge
- Force per unit charge
Show hintHide hint
Consider what happens to charges in an electric field.
4Question 4.
The formula to calculate electric potential is V = (1/4πε₀)(Q/r). (True/False)
- True
- False
Show hintHide hint
Recall the context of potentials derived from charges.
Question 5.
A 10 μC charge is situated at a point. Calculate the electric potential it creates at a point 1m away.
Show hintHide hint
Remember to substitute ε₀ with the value and perform the multiplication.
Question 6.
Two charges, +20 μC and -10 μC, are 2 meters apart. Find the electric potential at a point exactly halfway between them.
Show hintHide hint
Consider that potential is a scalar; you can add them directly.
