Answer:
The net electric field at the midpoint is 6.85 x 10^7 N/C.
Explanation:
q = − 8.3 μC
q' = + 7.8 μC
d = 9.2 cm
d/2 = 4.6 cm
The electric field due to the charge q at midpoint is
leftwards
The electric field due to the charge q' at midpoint is
The resultant electric field at mid point is
E'' = E + E' = (3.53 + 3.32) x 10^7 = 6.85 x 10^7 N/C
Complete Question

Answer:
The magnetic field is
And the direction is
Explanation:
From the question we are told that
The magnetic field at the center is
Generally magnetic field is mathematically represented as
We are told that it is equal to 1mT
So
From the first diagram we see that the effect of the current flowing in the circular loop is (i.e the magnetic field generated)
This implies that the effect of a current flowing in the smaller semi-circular loop is (i.e the magnetic field generated)
and for the larger semi-circular loop is
Now a closer look at the second diagram will show us that the current in the semi-circular loop are moving in the opposite direction
So the net magnetic field would be
Recall
So
Using the Right-hand rule we see that the direction is into the page which is
Answer:
a
b
Explanation:
From the question we are told that
The wavelength of the light is
The distance of the slit separation is
Generally the condition for two slit interference is
Where m is the order which is given from the question as m = 2
=>
substituting values
Now on the second question
The distance of separation of the slit is
The intensity at the the angular position in part "a" is mathematically evaluated as
Where is mathematically evaluated as
substituting values
So the intensity is
