In this lesson, we will learn how to calculate the absolute electric potential at different positions due to combinations of radial electric fields.
Q1:
Find the absolute electric potential at point 𝑃 shown in the diagram. Use 8.988×10 N⋅m2/C2 for the value of Coulomb’s constant. Give your answer in scientific notation to one decimal place.
Q2:
A particle has a charge of 2.5 mC. Find the absolute electric potential at a point that is 15 cm away from the particle. Use 8.988×10 N⋅m2/C2 for the value of Coulomb’s constant. Answer in scientific notation to one decimal place.
Q3:
Which of the following formulas correctly relates the absolute electric potential 𝑉 caused by a charged particle to the charge of a particle 𝑞, the distance from the particle 𝑟, Coulomb’s constant 𝑘, and the electric field due to a particle 𝐸?
