Two 18 cm -long thin glass rods uniformly charged to +18nC are
placed side by side, 4.0 cm apart. What are the electric field
strengths E1, E2, and E3 at distances
1.0 cm, 2.0 cm, and 3.0 cm to the right of the rod on the left,
along the line connecting the midpoints of the two rods?
Part A

Express your answer to two significant figures and include the
appropriate units.
Part B
Specify the electric field strength E2.
Express your answer to two significant figures and include the
appropriate units.
Part C
Specify the electric field strength E3.
Express your answer to two significant figures and include the
appropriate units.
