B. The electric potential at the given point from the proton is 2.7 x 10¹ volts

Electric potential of the proton

The electric potential of the proton is calculated as follows;

V = kq/r

where;

  • k is Coulomb's constant
  • q is charge
  • r is distance

V = (9 x 10⁹ x 1.6 x 10⁻¹⁹)/(5.3 x 10⁻¹¹)

V = 27.2 volts

V = 2.7 x 10¹ volts
