Suppose you have a 1.IμC point charge. A 50%
Part (a) How far in meters from the charge will the potential be 95 V if it is zero at infinity? A 50%
Part (b) How far in meters from the charge will the potential be 195 V? r2=_____m.

Answer 1

To find the distance from a point charge where the potential is a certain value, use the formula for electric potential: V = k * Q / r. For part (a) with a potential of 95 V, the distance is 1.168 m. For part (b) with a potential of 195 V, the distance is 0.626 m.

Step-by-step explanation:

To find the distance from a point charge where the potential is a certain value, we can use the formula for 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 from the charge. For part (a), we can rearrange the formula to solve for r:

r = k * Q / V

Substituting the given values: r = (9 x 10^9 Nm^2/C^2) * (1.1 x 10^-6 C) / (95 V)

r = 1.168 m

For part (b), we can use the same formula to find r:

r = (9 x 10^9 Nm^2/C^2) * (1.1 x 10^-6 C) / (195 V)

r = 0.626 m
