Explanation:
This question involves continuous displacement in various directions. When it becomes difficult to imagine, vector analysis becomes handy.
Let us denote each of the individual displacements by a vector. Consider the unit vectors as the unit vectors in the direction of East and North respectively.
By simple calculations, we can derive the unit vectors in the directions North,
South of West and
North of West respectively.
So Total displacement vector = Sum of individual displacement vectors.
Displacement vector =
Magnitude of Displacement =
∴ Total displacement =

Explanation:
From the question we are told that
The frequency of the radio station is
The magnitude of the magnetic field is
Generally the wavelength is mathematically represented as
Here c is the speed of light with value
So
=>
Generally the angular frequency is mathematically represented as
=>
=>
Generally the wave number is mathematically represented as
=>
=>
=>
Generally the amplitude of the electric field at this distance from the transmitter is mathematically represented as
=>
