Question 1 (1 point) Determine the total net charge in a closed system containing the following charges: 3.360 uC, -719.0 nC, and -0.006548 mc 3.360 uC O 10.63 uC -3.907 uC O -715.6 uCQuestion 2 [1 point} Two tiny charged particles are a distance d apart. Particle 1 has a charge of -1 nC, and particle 2 has a charge of +4 nC. Compare the magnitudes and directions of the forces on particle 1 by particle 2 and vice versa. [:1 Force on particle 1 is 4 times larger, two forces point in opposite directions 0 Two forces have same magnitude, point in opposite directions (2;) Force on particle 1 is 4 times larger, two forces point in same direction (22:) Two forces have same magnitude, point in same direction Question 3 (1 point) Two equally charged tiny spheres of mass 1.0 g are placed 2.0 cm apart. When released, they begin to accelerate away from each other at 414 m/s2. What is the magnitude of the charge oneach sphere, assuming only that the electric force is present? (k = 9.0E9 Nm2/C2) 75 nc 60 nc O 120 nC O 95 nc 140 ncQuestion 4 (1 point) You decide to charge an electroscope flask by induction, so you bring a positively charged rod next to the flask but don't touch it. You then ground the ball at the top. You then remove the grounding, and the rod. What is the charge on the electroscope flask? O Positive Negative O Neutral, but polarized into a positive and negative section Neutral, and not polarizedQuestion 6 (1 point) At the surface of the Earth, the gravitational field strength for an object Is directly proportional to that object's mass O Is inversely proportional to that object's mass Is constant, independent of the object's mass None of the aboveQuestion 7 (1 point} Electric field lines I1: :1 run from neutral object towards charged ones I:: :1 run perpendicular to the direction between positive and negative charges .;:_ :1 run from negative charge to positive charge ('3. run from positive to negative charge Question 8 [1 point} "The field strength is equal to the acceleration a particle would experience if it were placed in that field." Is this statement true for gravitational and electric fields? [:1 True for both (:1 True for gravitational, false for electric {:1 False for gravitational, true for electric [:1 False for both
