I am entering the answers in Webassign and it marked my answer as incorrect. I think there must be a mistake because no one I've showed it to has gotten a different answer.

Homework Statement A 1.5 10-9 C charge is at the origin, and a -1.50 10-9 C charge is 4.5 m to the right on the positive x-axis. The electric potential is -1.8 V at a point on the x-axis that is a distance d to the right of the negative charge. Find d. Homework Equations V = k [sum]...

Homework Statement The potential equals 7.52 V at the midpoint between two point charges that are 0.91 m apart. One of the charges is 1.11 x 10-9 C. Find the value of the other charge. Homework Equations V = k [sum] (q/r) The Attempt at a Solution 7.52=k[(1.11 x 10-9 / 0.455m ) + ( x /...

Homework Statement A solid sphere (S), a thin hoop (H), and a solid disk (D), all with the same radius, are allowed to roll down an inclined plane without slipping. At the bottom, they run into another inclined plane and begin rolling upwards. Which will travel the furthest up the inclined...
