Electric Current and Direct-Current Circuits
1* In our study of electrostatics, we concluded that there is no electric field within a conductor in electrostatic equilibrium. How is it that we can now discuss electric fields inside a co

Electrostatic Energy and Capacitance
1* Three point charges are on the x axis: q 1 at the origin, q 2 at x = 3 m, and q 3 at x = 6 m. Find the electrostatic potential energy for (a) q 1 = q 2 = q 3 = 2 C, (b) q 1 = q 2 = 2 C and q 3 =

Electric Potential
1*
A uniform electric field of 2 kN/C is in the x direction. A positive point charge Q = 3 C is released from rest at
the origin. (a) What is the potential difference V(4 m) V(0)? (b) What is the change in the pot

The Electric Field II: Continuous Charge Distributions
1* A uniform line charge of linear charge density ? = 3.5 nC/m extends from x = 0 to x = 5 m. (a) What is the total charge? Find the electric fie ld on the x axis at (b) x = 6 m, (c
