Both electric force and gravitational force are conservative and obey inverse square law.
The electric force between two charges q and q' separated by a distance r is calculated as-
Here K is the proportionality constant whose value is
The gravitational force between two masses m and m' separated by a distance r is given as -
Here K' is the proportionality constant whose value is G .
G is called gravitational force constant and its value is given
The electric force is a stronger force and gravitational force is a weaker force.
It is obvious that the value of constant for electric force is much larger than the gravitational force constant.
Out of the four options given in the question the the option four is the correct answer i.e D) The electrical force is much larger than the gravitational force because 10^9 is much greater than 10–11.
Answer:
D. move up to another shell that would form
Explanation:
An atom has protons, neutrons and electrons. Protons and neutrons are present in the nucleus and electrons orbit the nucleus in fixed shells. An electron can jump to higher shell when it gains energy and lower one when it loses energy. Thus, when single electron in hydrogen atom is given a small amount of energy, it would jump to another higher shell.
<span>Let F be the maximum thrust of the car's engine. Then F = ma = 1300 x 3.0 = 3900N. With the added load, F remains the same, but we now have F = 1700a giving a = F/1700 = 3900/1700 = 2.3 m/s².</span>
v1 = 6m/s
v2 = 0
∆v = v1 - v2 = 6m\s
s = t * v = 15m
t = s\v1 = 15(m) \ 6(m\s) = 2.5s
a = ∆v\t = 6(m\s) \ 2.5s = 2.4m\s2
a = F\m = 2.4m\s2
F = a * m = 2.4m\s2 * ?kg
I can't tell you this because I don't know the mass of this cyclist
