Step-by-step explanation:
The electrical force between two unlike charge is given by :

k is electrostatic constant
q₁ and q₂ are two charges
r is the distance between charges
It is clear that the electric force is inversely proportional to the square of the distance between them.
The graph F as a function of r for two positive charges is shown in the attached figure. It is a hyperbola.
(10 2/3)/(11/20)
(32/3)/(11/20)
(32/3)*(20/11)
640/33

Answer:
58, 37, 9
Step-by-step explanation:
Given:
First term a₁ = 65 and common difference d = - 7
This sequence is arithmetic series and formula for calculating n-th term is:
aₙ = a₁ + (n-1) d
Accordingly
The second term is:
a₂ = 65 + (2-1) (-7) = 65 - 7 = 58
a₂ = 58
The fifth term is:
a₅ = 65 + (5 - 1) (-7) = 65 + 4 · (-7) = 65 - 28 = 37
a₅ = 37
The ninth term is:
a₉ = 65 + (9 - 1) (-7) = 65 + 8 · (-7) = 65 - 56 = 9
a₉ = 9
God with you!!!
