Question 6 (1 point) Two charged spheres 64 cm apart attract each other with a force of 6.05 x 10-6 N. What force results from each of the following changes, expressed in micronewtons? An uncharged, identical sphere is touched to one of the spheres, and then taken far away while the distance remains the same. Record only the decimal part of the force expressed in the form (Decimal part)x10-6 N. Record the decimal part to two digits after the decimal point. No units Your Answer: Answer
3 -- 9 12 15 Question 7 (1 point) Two charged spheres 60 cm apart attract each other with a force of 6.74 x 10-6 N. What force results from each of the following changes, expressed in micronewtons? One charge is increased by a factor of 3.7, the other charge is decreased by a factor of 4.4 and the distance while the distance remains the same. Record the decimal part to two digits after the decimal point. No units Your Answer: Answer
Question 9 (1 point) Three objects, carrying charges of q1=-4.26 x 10-6C, q2= -4.08 x 10-6 C, and 93 +4.31 x 10-6 C, respectively, are placed in a line, equally spaced from left to right by a distance of 0.69 m. Calculate the magnitude and direction of the net force acting on q2 charge that results from the presence of the other two. State the negative sign if the net force is toward West. Your Answer: Answer
Question 10 (1 point) Two positive charges of 8.07 x 10-6 C are separated by 0.65 m. Calculate the magnitude of electrostatic force that each of the charges experience. Is this force repulsive or attractive? If it is repulsive then identify it with the negative sign. Record your answer to two digits after the decimal point Your Answer: Answer
Question 12 (1 point) Two pith balls shown in the diagram below have a mass of 5.7 g each and have equal charges. One pith ball is suspended by an insulating thread. The other charge is brought to within 65 cm. The suspended pith ball is deflected from its rest position until the thread forms an angle of 24.4" with the vertical. At this angle, the ball is in equilibrium. Calculate the Tension on the thread at the moment of equilibrium, in millinewtons. Round your answer to two digits after the decimal point. No units Your Answer: Answer
Question 13 (1 point) Two pith balls shown in the diagram below have a mass of 3.0 g each and have equal charges. One pith ball is suspended by an insulating thread. The other charge is brought to within 67 cm. The suspended pith ball is deflected from its rest position until the thread forms an angle of 38.5° with the vertical. At this angle, the ball is in equilibrium. Calculate the electrostatic force experienced by the pith ball at the moment of equilibrium, in millinewtons. Round your answer to two digits after the decimal point. No units Your Answer: Answer
Question 15 (1 point) Three objects, carrying charges of q1=-3.46 x 10-6 C, 92= -4.91 x 10-6 C, and 93=+8.15 x 10-6 C, respectively, are placed in a line, equally spaced from left to right by a distance of 0.77 m. Calculate the magnitude and direction of the net force acting on q₁ charge that results from the presence of the other two. State the negative sign if the net force is toward West. Your Answer: Answer Answer
