1.12 [2pt] Consider one infinitely long straight wire with auniform charge density of 1 C/m. Sketch the electric field aroundthe wire
1.12 ANSWER
1.13 [2pt] In problem 1.12, calculate the magnitude of electricfield at a distance R from the wire. How is it different (if any)from the field of a point charge?
1.13 ANSWER
1.14 [2pt] Consider two infinite wires 1 m apart with a uniformcharge density per unit length 1 C/m. Calculate the force per unitlength between the wires. To do this, just select a tiny, nearlypoint-like section of a wire of length Land calculate the force dueto the electric field of the other wire using the Coulomb’s law.Your answer should be proportional to L. Divide it by L and this isthe force per unit length.
