Questions & Step-by-Step Solutions

What is the electric potential at a point due to a point charge?
  • 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.
