A straight wire, labeled as Wire A, lies horizontally on a tabletop and is oriented to run north-south. A conventional current of 1.0 amperes runs in the wire directed towards the north. A second wire, labeled as Wire B, is also laid on the tabletop oriented north-south. Which of the following statements is true?
(i) If Wire B carries no current in it and lies to the left (west) of wire A, then it will experience an attractive force to the right (towards wire A).
(ii) If Wire B carries a northward conventional current and lies to the left (west) of wire A, then it will experience an attractive force to the right (towards Wire A).
(iii) If Wire B carries a northward conventional current and lies to the right (east) of wire A, then it will experience a repulsive force to the right (away from Wire A).
(iv) If Wire B carries a southward conventional current and lies to the left (west) of wire A, then it will experience a repulsive force to the left (away from Wire A).
Select the correct
a. Only statements (i), (ii) and (iii) are true.
b. Only statements (i) and (iii) are true.
c. Only statements (ii), (iii), and (iv) are true.
d. Only statements (ii) and (iv) are true.
e. All statements are true
f. None of the statements are true.

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
