Consider a charge of size +3.8 x 10-4 C and mass 8 kg is traveling to the left towards a +1.7 x 10-4 C charge with speed 119 m/s. The +1.7 x 10-4 C charge is so massive that it does not recoil in response to the repulsion of the approaching charge. Calculate how close the two charges get, in m. Use k = 9 x 109 N m2 / kg2.
(Please answer to the fourth decimal place - i.e 14.3225)
A hydrogen atom when in its lowest energy state consists of a proton nucleus of charge +e (remember that +e = 1.6 x 10-19 C) and an electron of charge -e and mass of
9.1 x 10-31 kg. In the Bohr model of the atom, the electron moves around the nucleus in an approximately circular orbit with a radius of 0.52 x 10-10 m. The speed of the
electron when in this lowest energy orbit is approximately 2.3 x 106 m/s.
Imagine that we want to ionize this atom (that is free up the electron from its nucleus) by launching ANOTHER electron at the atom to break it apart. If we were to launch
this electron from very far away from the atom, then how fast must it be launched in order to break apart the atom, so that all three particles (the proton and two
electrons) end up at rest, very far apart?
An unknown particle is measured to have a negative charge and a speed of 2.24
x 108 m/s. Its momentum is determined to be 3.07 × 10-22 kg-m/s. Identify the
particle by finding its mass.

- A 212^Bi (bismuth) nucleus undergoes alpha decay, resulting in a 208^Tl (thallium) nucleus and a 4He (helium) nucleus as per the following reaction: 212^Bi →208^Tl + 4^He The masses of each nucleus is listed in the table below.

- The gravitational force between two masses m and m2 located a distance r apart has a magnitude of FG =Gmm2, where G = 6.674×10 N ⋅ m2/kg2; this has a nearly identical form to the Coulomb force law between two charges (except the force constants are different and masses are always positive). Suppose two identical spherical masses with radius a = 30 μm and mass density ρm = 2.2 × 103 kg/m3 are located a distance L apart. If they are released rest, their gravitational attraction will cause them to eventually collide. If, however, each mass has the same charge, then a Coulomb force will oppose the gravitation force. Suppose each mass has an excess of n extra electrons that causes both to be negatively charged. Find the minimum number n that would prevent the masses from colliding.arrow_forwardQ. 3.
