The drawings show three charges that have the same magnitude but may have different signs. in all cases the distance d between the charges is the same. the magnitude of the charges is |q|= 1.7 μc, and the distance between them is d = 1.9 mm. determine the magnitude of the net force on charge 2 for each of the three drawings.

a) F= 14393.96N

b) F= 0

q1 pulls while q3 pushes

c) F= 10,178.07N

Explanation:

a) F = 2× (8.99×10^9)×[(1.7×10^-6)^2/(0.0019)^2]

F= (1.789×10^10 ) × (2.89×10^-12)/(3.61×10^-6)

F= 14393.96N

q1 pulls while q2 pushes.

b) By symmetry, F= 0

q1 and q2 both pushes

c) a) is perpendicular instead of parallel, therefore F = 14393.93/(sqrt2)

F= 10,178.07N

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

it doesn't. it was imagined up in the middle ages.
