A uniformly charged thin ring has radius 14.0 cmand total charge 22.0 nC . An electron is placed on the ring's axis a distance 34.5 cm from the center of the ring and is constrained to stay on the axis of the ring. The electron is then released from rest.

Part A Describe the subsequent motion of the electron.

Part B Find the speed of the electron when it reaches the center of the ring.

a. The Electron will begin to move along the axis, towards the center and velocity of it is instantaneous because the force acting on it depends on x and the acceleration as well until it reaches maximum velocity at the center.

b. Vb= 1.6 * 10^7 m/s^2

Explanation:

See picture

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
