1) Experimentor A uses a test charge qsub0 and experimentor B uses a test charge 2qsub0 to measure an electric field produced by stationary charges. A finds a field that is:
ans: The same as the field around B - WHY?
2) An isolated point charges point particle produces an electric field with magnitude E at a point 2m away from the charge. A point at which the field magnitude is E/4 is:
A) 1 m away from the charge
b) 0.5 m away from the charge
c) 2m away from the charge
d) 4 m away from the charge
e) 8 m away from the charge
3) An isolated charges point particle produces an electric field with magnitude E at a point 2m away. At a point 1 m from the particle the magnitude of the field is:
a) E
b) 2E
c) 4E
d) E/2
e) E/4
