P2114) At each corner of a square of side l there are point charges of magnitude Q, 2Q, 3Q, and 4Q (Fig. 2149). Determine the force on each charge due to the other three charges. P2133) Draw, approximately, the electric field lines emanating from a uniformly charged straight wire whose length l is not great. The spacing between lines near the wire should be somewhat less than l. [Hint: Also consider points very far from the wire.] P2137) Use Coulombs law to determine the magnitude and direction of the electric field at points A and B in Fig. 2152 due to the two positive charges (Q = 7.0 m C) shown. Is your result consistent with Fig. 2133b?...
