The electric field is expressed as:
, where E is the electric field, k is Coulomb's constant, q is the charge, and r is the distance.
The electric field, E = < 0, 5. 104, 0> N/C is in the y-direction only.
This means that the electric field in the x-direction and z-direction is zero.
The charged particle will be placed only on the y-axis.
You want to create an electric field = < 0, 5. 104, 0> N/C at location < 0, 0, 0>.
A. Where would you place a proton to produce this field at the origin?
p = m
B. Instead of a proton, where would you place an electron to produce this field at the origin?
e = m
(Hint: This problem will be much easier if you draw a diagram.)
