An electric field of magnitude 5.25 x 10' N/C points due south at a certain location. Find the magnitude and direction of the force on 3-5.85 C charge at this location. magnitude IN direction -Selech Four point charges are located at the corners of a square. Each charge has magnitude 3.10 nC and the square has sides of length 2.10 cm. Find the magnitude of the electric field in N/C) at the center of the square if all of the charges are positive and three of the charges are positive and one is negative. HINT (a) all the charges are positive NC (b) three of the charges are positive and one is negative N/C

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio ρ1/ρ2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?
