The figure shows an electron having small axial oscillationswith an amplitud of 1.0μm around z=0. the total chargeof the ring is Q=10μC and its radius is 0.1mm.

a)the frequency of oscilation
b)the maximum speed
c)the energy of the electron
d)the function of electric potential V(z)

hint: use z<<R to get the approximation ~ R and with this way express theforce of the electron as F(z) ~ -Kz

Using your favorite graphing software: graph V(z) for-1.0μmz+1.0um and show that the point z=0 is apoint with stable equilibrium.

MAJOR HELP ON THIS ONE PLEASE!!! its a veryimportant assignment for Monday!
