Q: What is the electrostatic potential at a point due to a point charge Q located at a distance r from the charge? (2021)
Solution:
The electrostatic potential V at a distance r from a point charge Q is given by V = kQ/r, where k is Coulomb's constant.
Steps: 6
Show Steps
Step 1: Understand that a point charge Q creates an electric field around it.
Step 2: Know that the electrostatic potential V is a measure of the potential energy per unit charge at a point in the electric field.
Step 3: Identify the distance r from the point charge Q to the point where you want to find the potential.
Step 4: Use the formula for electrostatic potential, which is V = kQ/r.
Step 5: Recognize that k is Coulomb's constant, approximately equal to 8.99 x 10^9 N m²/C².
Step 6: Plug in the values of Q and r into the formula to calculate the electrostatic potential V.
