(1)Which of the following statements about electric field lines is false? a) They are perpendicular to the surface of an isolated conductor b) They never intersect c) They indicate the path along which a test charge moves d) More indicate a stronger field e) They can be either straight or...

Ahhh! Fantastic, yes that makes sense to do twice the field strength because both fields contribute. Great! Thank you very much sleepy time, much appreciated

Two long current-carrying wires cross at an angle of 21° ("theta" is half of this) as shown in the figure above. The magnitude of the current is the same in each wire, I=400 A. A wood mouse is running along the dashed line midway between the wires towards the point where the wires cross...
