Answer:
so the distance between two points are

Explanation:
Surface charge density of the charged plane is given as

now we have electric field due to charged planed is given as

now we have


now for the potential difference of 100 Volts we can have the relation as




Answer and working shown on photo, final answer for number electrons=2.5*10^17 electrons
If you are referring to science, then you are correct. A period is also known as a family.
Answer:
3.2 m
Explanation:
The equation to use to solve this problem is:

where
is the final velocity
is the initial velocity
a is the acceleration
is the distance covered
For the particle in free-fall in this problem, we have
(it starts from rest)

(acceleration due to gravity)
By re-arranging the equation, we can find the distance travelled:

Potential Energy = mass x gravitational acceleration x height
potential Energy = 1 x 9.8 x 10 = 98 joules
