Scientists calculate the centripetal force on an electron travelling around a nucleus to be 7.632x10-°N. Given that the diameter of
the electron's orbit is 1.06x10-1ºm, calculate the frequency with which the electron circles the nucleus.
In introductory physics laboratories, a typical Cavendish balance for measuring the gravitational constant G uses lead spheres with masses of 1.20 kg and 12.0 g whose centers are separated by about
4.90 cm. Calculate the gravitational force between these spheres, treating each as a particle located at the center of the sphere.

- A uniform distribution of dust in the solar system adds to the gravitational attraction of the Sun on a planet an additional forceF = −m C rwhere m is the mass of the planet, C is a constant proportional to the gravitational constant and the density of the dust, and r is the radius vector from the Sun to the planet (both considered as points). This additional force is very small compared to the direct Sun-planet gravitational force.

In the future, there will be need for satellites in synchronous orbit around Mars to aid colonies.

(Hint: if you haven’t had a physics class before, you can find this by using the fact that the acceleration of an object in circular motion either as v2/r, where v and r are the velocity and radius of the orbit, or as 4Pi 2r/T2 , where T is the period.
