Introduction

Electric potential, also known as voltage, is a measure of the potential difference in electric potential energy per unit charge between two points in a electric field. It is an important concept in physics, particularly in the study of electricity and magnetism. In this article, we will explore the relationship between electric potential and distance from a point charge.

Electric Potential Due to a Point Charge

The electric potential due to a point charge is given by the equation:

V = \frac{kQ}{r}

where:

V is the electric potential in volts (V)
k is Coulomb's constant, approximately equal to $$9.00 \times 10^9$$ N m^2 C^-2
Q is the charge in coulombs (C)
r is the distance from the charge in meters (m)

Calculating the Distance

We are given a charge of $$1.00 \times 10^{-5}$$ C and an electric potential of 10,000 V. We can use the equation above to calculate the distance from the charge.

Rearranging the equation to solve for r, we get:

r = \frac{kQ}{V}

Substituting the given values, we get:

r = \frac{(9.00 \times 10^9) (1.00 \times 10^{-5})}{10000}

r = \frac{9.00 \times 10^4}{10000}

r = 9.00

Conclusion

Therefore, the distance from a $$1.00 \times 10^{-5}$$ C charge at which the electric potential will be 10,000 V is 9.00 meters.
