An alpha particle (α), which is the same as a helium-4 nucleus, is momentarily at rest in a region of space occupied by an electric field. The particle then begins to move. Find the speed of the alpha particle after it has moved through a potential difference of −3.45×10^−3 V. The charge and the mass of an alpha particle are qα = 3.20×10^−19 C and mα = 6.68×10^−27 kg , respectively.
Mechanical energy is conserved in the presence of which of the following types of forces?
Select all that apply.
A- electrostatic
B- frictional
C- magnetic
D- gravitational
Part B- Which of the following quantities are unknown?
A- the initial speed of the alpha particle
B- the value of the electric potential at the initial position of the alpha particle
C- the value of the electric potential at the final position of the alpha particle
D- the final speed of the alpha particle
E- the charge of the alpha particle
F- the difference in potential between the initial and final positions of the alpha particle
G- the mass of the alpha particle
Part C- Use conservation of energy (Ki+qVi=Kf+qVf) to solve for the final kinetic energy. Then use this value to solve for the final velocity of the alpha particle.

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
