Question

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 nC are placed side by side, 4.30 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?

Answer 1

Answer: 354311 N/C, 275095 N/C, 458528 N/CExplanation:E = kQ/[r * √(r² + L/2)²], where L = 10 cm = 0.1 mE = kQ/[r * √(r² + 0.05²)]For the glass rod,E at 1 cm = E = k * 15*10^-9 / [0.01 * √…
