Answer: electric potential difference
Explanation:
Answer:
q₁ = q₂ = Q = 14.8 pC
Explanation:
Given that
q₁ = q₂ = Q = ?
Distance between charges = r =7.3 cm = 0.073 m
Combined electric field = E₁ + E₂ = E = 50 N/C
Using formula

Rearranging for Q


Answer: 

Explanation:
Firstly, let's convert these length to meters
, in order to work with the same units:
a. 400 millimeters

b. 22 kilometers

c. 170 meters
Here the lenght is already in meters
d. 3.3 centimeters

Now that we have all the lengths in meters, we can order them from shortest to longest:

or

Answer:
206 pm
Explanation:
We are given that
Potential difference,
Distance,d=
We have to determine the de Brogile wavelength of the electron.
A=11 and B=5


Charge on electron,q =
Mass of electron=m=
Speed of electron,
Using the formula

v=
de Brogile wavelength, 
Where 

1 pm=
