Question

CR-RI-R2- DR-IR1-IR2+IR (2) In Figure, are capacilioes 1 and 2 in eries AC-C1+C2-C3 CR-RI-R2-R3 (4) In Couloenb's law, two positive charges each other A repel B attract C no force (5) In defining an electric field, a test charge is used. Is the test charge positively or s charged? Which describes the direction of the electric field vector? A Negatively charged. The field vector is in the samse direction as the force on the te B Positively charged. The field vector is in the same direction as the force on the test

Explanation / Answer
