Question

(1)(A)When removing a wool sweater, a static discharge of 8.83 µC dissipates 7.52 10^-3 J of energy. What voltage was involved?

(B)Two protons are released from rest, one from location 1 and another from location 2. When these two protons reach location 3, the first proton has a speed that is 4 times the speed of the second proton. If the electric potentials at locations 1 and 2 are 231 V and 115 V, respectively, what is the electric potential at location 3?

(C)two charges q₁ = +q and q₂ = −2q are fixed in place. The distance between them is d = 2.32 m. Find the distance x of the point A on the horizontal line where the net electric potential due to the two charges is zero.

(D)Find the capacitance of a parallel plate capacitor having plates of area 4.80 m² that are separated by 0.420 mm of Teflon. The dielectric constant of Teflon is 2.1.
