Answer
In this question we have given,
Height of plane, h1=2000m
Height at which charge concentration is 40C, h2=3000m
Height at which charge concentration is -40C, h3=1000m
charge concentaration, q1=40C
charge concentaration, q2=-40C
let the charge concentrations at height h2 and h3 as point charges
Now we will first find the electric feild on plane due to positive charge q1=40
Here k=8.98755*10^9N.m^2/C^2
q1=40C
put values of k, q1 , h1 and h2 in equation 1
\\
V/m[/tex]
similarly electric feild due to negative charge q2=-40
\\
Total electric feild E at the aircraft is given as
...............(2)
Put values of E1 and E2 in equation2
therefore s Total electric feild E at the aircraft is E= 719004V/m
Answer:
The magnitude of the Force is and the direction is South
Explanation:
From the question we are told that
The magnetic field point due west and since East point toward the positive x -axis then this magnetic field would be mathematically represented as
Now from the question we are told that the kinetic energy is
Now this kinetic energy can be mathematically represented as
Where m is the mass of proton which has a general value of
Now making the subject of the formula
Substituting values we have
Now from the question we are told that proton is moving upward which is in the positive z direction so the velocity of the proton would be in the positive
So the velocity would be
Now the magnetic Force can be mathematically represented as
Where q is the charge on the proton which has a general value of
Now substituting the value
Now according to Fleming's left hand rule the direction of the magnetic force is south toward the negative Y - direction
So the force can be denoted as
