Question

A pair of parallel, horizontal metal plates have a field between them given by  = 122ĵ N/C.

At some instant an electron moving between the plates has velocity  = (152?̂ + 3.38?̂) × 10³ m/s.

Determine:

a. the electron’s initial acceleration;       = ( Blank 1. Calculate the answer by read surrounding text. ?̂ +  Blank 2. Calculate the answer by read surrounding text. ?̂) m/s²

b. the velocity of the electron after it’s x-position has changed by 2.00 cm.      = (  Blank 3. Calculate the answer by read surrounding text. ?̂ +  Blank 4. Calculate the answer by read surrounding text. ?̂) m/s

How would your answers above differ if the moving particle was a proton?    Difference = Blank 5. Calculate the answer by read surrounding text.
1 = Not at all
2 = Both would be greater
3 = Both would be smaller
4 = The acceleration would be smaller, but the velocity after 2 cm would be greater
