PHY 102 Coulomb's law and Electric Fields Objective Question

Question

How is the absolute potential at a point P due to a point charge q₀, at a distance r in vacuum, calculated?
Options
A V = k₀q₀r
B V = k₀q₀/r
Correct Answer
C V = k₀q₀/r²
D V = k₀r/q₀
Correct Answer

Option B is the correct answer.

Detailed Explanation

On page 10, the text states: 'The absolute potential at P due to the charge q₀ is V = k₀q₀/r'.

Hint

The formula for absolute potential due to a point charge involves the Coulomb constant, the charge, and the distance, but pay attention to the exponent of r.
