Questions
Three long, straight parallel wires carrying current, are arranged as shown in figure. The force experienced by a 25 cm length of wire C is
detailed solution
Correct option is C
Force on wire C due to wire D,FD= 10−7 × 2 × 30 × 103 × 10−2×25 × 10−2 = 5 × 10−4N (Towards right)Force on wire C due to wire G,FG= 10−7 × 2 × 20 × 102 × 10−2×25 × 10−2 = 5 × 10−4N⇒ Net force on wire C is Fnet = FD −FG=0(Towards left)Talk to our academic expert!
