Awire carries 3.7 a of current. a second wire is placed parallel to the first 8.0 cm away. what is the current flowing through the second wire if the magnitude of the wires is zero at a distance 3.4 cm from the first wire. o 11 a 5.0a o 5.7a o 3.7a

The current in second wire is 5.0 A.

(B) is correct option.

Explanation:

Given that,

Current in first wire = 3.7 A

Distance = 8.0 cm

We need to calculate the magnetic field due to the current carrying wire

Using formula of magnetic field

Where, I = current

r = distance

Put the value into the formula

For first wire

...(I)

For second wire,

The distance is 8-3.7 =  4.3 cm

...(II)

The magnetic field in both the wires,

From equation (I) and (II)

Hence, The current in second wire is 5.0 A.

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.
