Answer:
Explanation:
Magnetic field near current carrying wire
=
i is current , r is distance from wire
B = 10⁻⁷ x
force on second wire per unit length
B I L , I is current in second wire , L is length of wire
= 10⁻⁷ x x 33 x 1
= 3234 x
This should balance weight of second wire per unit length
3234 x = .075
r = x 10⁻⁷
= .0043 m
= .43 cm .
