Questions & Step-by-Step Solutions

What is the electric potential at a point due to a charge Q at a distance r? (2021)
  • Step 1: Understand that electric potential (V) is a measure of the potential energy per unit charge at a point in space due to a charge.
  • Step 2: Identify the charge (Q) that is creating the electric potential.
  • Step 3: Determine the distance (r) from the charge to the point where you want to find the electric potential.
  • Step 4: Use the formula for electric potential, which is V = kQ/r, where k is a constant (Coulomb's constant).
  • Step 5: Plug in the values of Q and r into the formula to calculate the electric potential (V).
