ou Answered rrect Answer Three point charges are arranged as in the figure. Charge q₁ = 1.88 nC is at the origin, 92 = 4.37 nC is at №₂ = 78.6 µm, and q3 = -8.5 nC is at x3 = -90.3 um. Calculate the magnitude (in N) of the net electrostatic force on charge 91. X 29.58 L2 21.2867 margin of error +/- 1%
Two point charged objects A (with charge qa = +4µC) and B (with charge q +7µC) are separated by a distance 2d. Therefore, Coulomb force on A and B created as FAB and FBA where ma and mg are the mass of A and B, may be expressed as O FAB / FBA = (7/4)2 FAB / FBA = 7/4 O FAB / FBA = 1 O FAB / FBA = 4/7
QUESTION 19 The initially-neutral, conducting, solid object diagrammed below contains two inner cavities. A point charge, +7Q is then placed in one of the cavities while a point charge of -3Q is placed in the other cavity. (Q > 0) What resultant charge resides on the outer surface of the conductor after the conductor is allowed to reach electrostatic equilibrium? +7Q -3Q а. +4Q b. -3Q Ос. -4 d. +7Q е. -3Q

Consider the point charges arranged at the corners and at the center of a square, as depicted in the figure. O qa qc Oa qb O qd = Find the magnitude of the net Coulomb force, in newtons, on the charge q in the figure, given that q = 1.2 μC, 9a = 2.6 µC, qb= -3.6 µC, qc = -5.1 µC, and qd 0.65 µC. The square is 43 cm on a side. |F|=||
Two point charges, -25 uC and -75 µC, are held fixed exactly 1.0 m apart. (a) Where should a third charge be placed so that the net force on it is zero? (b) Explain why the magni- tude and sign of the third charge do not affect your answer to part (a).
Two electrically charged bodies of the same sign 5 μC and 10 μC respectively are separated by 20 cm in a vacuum. Calculate at what point inside or outside the imaginary line that joins them a third negative charge of 5 μC should be placed so that the total force on this is zero ans. 8.28 cm
