Answer:
magnitude of net magnetic field at given point is

Explanation:
As we know that magnetic field due to a long current carrying wire is given as

here we we will find the magnetic field due to wire which is along x axis is given as

r = 2 m
now we have

into the plane
Now similarly magnetic field due to another wire which is perpendicular to xy plane is given as

r = 2 m
now we have

along + x direction
Since the two magnetic field is perpendicular to each other
So here net magnetic field is given as


Answer:
0.000507 kg/m
Explanation:
L = Length of string
T = Tension
= Mass density of string
E denotes the E string
D denotes the D String
Frequency is given by

So


The mass density of the E string is 0.000507 kg/m
