Q: A spherical conductor has a radius R and carries a charge Q. What is the electric potential on its surface?
Solution: The electric potential V on the surface of a charged spherical conductor is given by V = kQ/R.
Steps: 5
Step 1: Understand that a spherical conductor is a shape that can hold electric charge evenly distributed on its surface.
Step 2: Recognize that the electric potential (V) is a measure of the electric energy per unit charge at a point in space.
Step 3: Know that for a spherical conductor, the electric potential at its surface depends on the total charge (Q) it carries and its radius (R).
Step 4: Remember the formula for electric potential on the surface of a charged spherical conductor: V = kQ/R, where k is a constant (Coulomb's constant).
Step 5: Substitute the values of Q (the charge) and R (the radius) into the formula to find the electric potential V.
