1. A pair of metal plates, mounted 1.0 cm apart on insulators, is charged oppositely. A test charge of +2.0 uC placed at the midpoint, M, between the plates experiences a force of 6.0 x 104N [W].
a. What is the electric field intensity at M?
b. What is the electric field intensity at a point 2.0 mm from the negative plate?
c. What is the electric field intensity at a point 1.0 mm from the positive plate?
d. What are two possible ways in which you could double the strength of the electric field?
