C) An electric dipole is formed from two charges, ±q, spaced 1.30 cm apart. The dipole is at the origin, oriented along the y-axis. The electric field strength at the point (x,y)=(0cm,10cm) is 330 N/C .

- What is the charge q? Give your answer in nC.

- What is the electric field strength at the point (x,y)=(10cm,0cm)? Express your answer with the appropriate units.

D) A small glass bead charged to 4.5 nC is in the plane that bisects a thin, uniformly charged, 10-cm-long glass rod and is 4.0 cm from the rod's center. The bead is repelled from the rod with a force of 840 μN.

- What is the total charge on the rod?

Express your answer with the appropriate units.
