Two 10 cm long, straight wires, each carrying a current of 5A are kept parallel to each other. If each wire experienced a force of 10 -5 N, then separation between the wires is_________cm.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(5)
It should be mentioned, 10 cm wire is part of long wire.
Force experienced by unit length of wire
Force experienced by wires of length 10 cm
d = 50 x 10 -3 m
d = 50 x 10 -1 cm = 5cm.
