Answer:
The width of the sheet is
Explanation:
From the question we are told that
The distance of point P above a large sheet of metal is
The current on the large metal sheet is
The distance of the the point P below a long wire
The current on the long wire is
The magnetic field at P is
Generally magnetic field of P long wire is mathematically represented as
Generally magnetic field of P large sheet of meta is mathematically represented as
Where K is the current per unit width
The total magnetic field at P is
Making K the subject of formula
Substituting values
Generally K is mathematically represented as
Where w is the width of the large sheet
Therefore the width of the metal sheet
