Answer: d
Explanation: V = Q/(4πεr), where r = 1m
V = (2 X 10-9)/(4πε x 1) = 18 volts
Explanation: V = Q/(4πεr), where r = 1m
V = (2 X 10-9)/(4πε x 1) = 18 volts

Potential at a Point Due to a Point Charge
To find the potential at a point (1,0,0) due to a point charge located at the origin, we can use the formula for the electric potential:
V = k * q / r
where V is the potential, k is the Coulomb's constant (9 x 10^9 Nm^2/C^2), q is the charge, and r is the distance between the point charge and the point where potential is being calculated.
Given Data:
- Charge (q) = 2 nC = 2 x 10^-9 C
- Distance (r) = 1 (since the point is located at (1,0,0))
Calculating the Potential:
Substituting the given values into the formula, we have:
V = (9 x 10^9 Nm^2/C^2) * (2 x 10^-9 C) / 1
Simplifying the equation, we get:
V = 18 Nm^2/C
Therefore, the potential at the point (1,0,0) is 18 Nm^2/C.
Answer:
The correct answer is option 'D' - 18.
