Two charges q = +4.8 μC are fixed a distance d = 6.2 cm apart (see the figure). (a) With V = 0 at infinity, what is the electric potential at point C ? (b) You bring a third charge q = +4.8 μC from infinity to C. How much work must you do? (c) What is the potential energy U of the three-charge configuration when the third charge is in place?

You drop a 2.40 kg book to a friend who stands on the ground at distance D = 13.0 m below. If your friend's outstretched hands are at distance d = 1.70 m above the ground (see the figure), (a) how much work Wg does the gravitational force do on the book as it drops to her hands? (b) What is the change ΔU in the gravitational potential energy of the book-Earth system during the drop? If the gravitational potential energy U of that system is taken to be zero at ground level, what is U (c) when the book is released and (d) when it reaches her hands? Now take U to be 100 J at ground level and again find (e) Wg, (f) ΔU, (g)U at the release point, and (h) U at her hands.

Figure below shows a ring of outer radius R = 13.0 cm and inner radius rinner = 0.200R. It has uniform surface charge density σ = 6.20 pC/m2. With V = 0 at infinity, find the electric potential at point P on the central axis of the ring, at distance z = 2.00 R from the center of the ring. (a) Start with the formula for the potential: V = k∫dQ |r→ − r→′| What is your dQ? What is your infinitesimal area element? What are your vectors r and r′ ? What is the distance to point P ? What is dV ? Potential due to a small ring of charge on the disk? (b) Write out the integral that you need to compute to get V. What are the bounds? (c) Once you get an expression for V, solve numerically. (d) Check to see if the units of your expression makes sense for V.
