A1. For problem 21.57, write a formula for the position vector
of the electron as a function of time,
r⃗(t)r→(t), using unit vector ("i-hat"
and "j-hat") notation. Assume the electron starts at the origin of
your coordinate system at t = 0, so
r0→=0iˆ+0jˆ.
(Hint: Use equation 3-13b from the textbook.)
