A 10-cm-long thin glass rod uniformly charged to 15.0 nC and a 10-cm-long thin plastic rod uniformly charged to - 15.0 nCare placed side by side, 4.50 cm apart. What are the electric field strengths E1 to E3 at distances 1.0 cm, 2.0 cm, and 3.0 cm from the glass rod along the line connecting the midpoints of the two rods?

Step 1

__Given:__

Length of each rod = 10 cm

Charge in glass rod = 15 nC

Charge on pastic rod = - 15 nC

Distance between the rods = 4.5 cm

Step 2

Writing the Electric field at a distance ‘r’ in front of the charged rod:

Step 3

Calculating the electric field between the rods at a distance 1 cm from the glass rod:

Let&rsquo...
