The electric field of a charge is defined by the force on: An electron A probe charge A proton. A source charge.
1 answer:
Answer:
A probe charge
Explanation:
As we know that electric field intensity is the force experienced by the probe charge which is placed in the electric field region
Here we can say it as
so here that probe charge should be very small so that it will not disturb the electric field in the space.
If the probe charge is of large magnitude then the field will get disturbed and the intensity which is to be measured is different from its actual value.
Also the sign of the probe charge is taken to be positive.
so correct answer here will be
A probe charge

Explanation:
From the question we are told that
Their distance apart is
The wavelength of each source wave
Let the distance from source A where the construct interference occurred be z
Generally the path difference for constructive interference is
Now given that we are considering just the straight line (i.e points along the line connecting the two sources ) then the order of the maxima m = 0
so
=>
=>
Generally the path difference for destructive interference is
=>
=>
substituting values
=>
So
and
=>
