Answer for Ch. 22, 8P
q1 = - 4 q2
Answer for Ch. 22, 10P
horizontal component: 0.17 N to the right
vertical component: 0.046 N down
Answer for Ch. 22, 18P
q = Q/2
Answer for Ch. 22, 19P
a) Q = - 2 sqrt(2) q
b) For both the force on Q and the force on q to vanish, we would require that
Q = - 2 sqrt(2) q and
q = - 2 sqrt(2) Q
be satisfied simultaneously which is not possible unless q = Q = 0.
