Q: What is the electric potential at a point due to a point charge?
Solution:
The electric potential V at a distance r from a point charge Q is given by V = kQ/r, where k is Coulomb's constant.
Steps: 5
Show Steps
Step 1: Identify the point charge (Q) you are interested in.
Step 2: Measure the distance (r) from the point charge to the point where you want to find the electric potential.
Step 3: Use Coulomb's constant (k), which is approximately 8.99 x 10^9 N m²/C².
Step 4: Plug the values of Q and r into the formula V = kQ/r.
Step 5: Calculate the value of V to find the electric potential at that point.
