electron that are 8.4 10-11 m apart. (Enter the magnitude
only.)

Compare this to the gravitational force between these
particles.

Compare the gravitational attraction (Newton's Law) and
electrical attraction (Coulomb's law) forces between an electron
and a proton, including the states of two electrons and two
protons. (You can refer an academic source for the load and mass
values of the particles)

Calculate and compare the electric force between a proton and
an electron to the gravitational force between a proton and an
electron located 10-12m apart. (answer:
Fg~10-43N and Fe~10-4N)

wall.

In a Hydrogen atom an electron rotates around a stationary
proton in a circular orbit with an approximate radius of r
=0.053nm. (a) Find the magnitude of the electrostatic force of
attraction, Fe between the electron and the proton. (b) Find the
magnitude of the gravitational force of attraction Fg , between the

If a proton and an electron are released when they are
1.50×10−10 m apart (typical atomic distances), find the
initial acceleration of each of them.
a)Acceleration of electron
b)Acceleration of proton

Newton’s Gravitational Law predicts the force of attraction
between two massive objects that are some distance apart: Fgravity
= G m1m2/ r^2
(a) Given F is in units of Newtons, m is units of kilograms and
r is in units of meters, what are the units of the universal
gravitational constant, G, in meters, kilograms and seconds? Show
your working.[2]
(b) If one of the objects doubles in mass, how much does the
predicted force of attraction change between the...

1. The product of the magnitude of one charge of the dipolar
distribution and the distance between the charges is called?
A. the dipole moment
B. the Debye constant
C. the electrical potential energy
D. none of the above
2. Which of the following is not true? The electric force
a. decreases with the inverse of the square of the distance
between two charged particles
b. between an electron and a proton is much stronger than the
gravitational force between...

A proton of mass mp = 1.67 × 10-27 kg and charge qp = 1.602 ×
10-27 C is in an electric field of E = 10 N/C that points upwards.
Draw a free body diagram for the proton, and calculate the
electrical-to-gravitational force ratio: FE/FG. Finally, remark on
whether the gravitational force is likely to be significant for an
electron in an 10 N/C electric field.

In Bohr's model for the Hydrogen atom, the electron when it is at the third level rotates in a circular orbit around the proton, at a radius of 4.7 x 10^-10 m. The proton has a positive electric charge of 1.6 x10^-19 C, while the electron has the same charge with an opposite sign. The electrical force between the two particles is responsible for the centripetal force that keeps the electron in its orbit. The mass of the proton is...
