The electrons in an atom exist in various energy levels. When an electron moves from a lower energy level to a higher energy level, energy is absorbed by the atom. When an electron moves from a higher to a lower energy level, energy is released (often as light).
Answer:
charge will be equal to
Explanation:
We have given mass of the particle m = 1.45 gram = 0.00145 kg
Acceleration due to gravity
Electric field E = 700 N/C
Electric force will be equal to , here q is charge and E is electric field
For particle to be stationary this force must be equal to force due to gravity , that is mg force
So qE = mg
So charge will be equal to
25/2=12.5
12.5 N is equal to 1 centimeter
Plug in 12.5 in for whatever the value of the centimeter is
Example
i want to know how many Newtons of force are needed to get 5 cm of extension
12.5*5=62.5
This is all i've got for your question because its not very specific.
Good Luck
