Electrons got ejected out as if they were ping pong balls by the light particle (photon). Electrons were not moving initially. Then, it was moving later because of the light.
a. what is the momentum of the electron initially (p=mv) Hint: Is it moving initially?
b. does the electron have momentum after being hit by the light particle? Hint: is it moving after being hit?
c. what can you infer about light particles in momentum? Hint: where is the electron getting its velocity from?

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?
