Answer #1

q1=4.0 uC

q2=6.0 uC

x=3.0 m

(a) the electic force on charge q2

F = kq1q2 / x2

q1 and q2 are charges x is distance between them. k = 9 x 109

electic force on charge q2

   (in this case both q1 and q2 will repel each other)

(b)

the electric force on q2

the electric force on q1

(in this case both q1 and q2 will repel each other and will move apart)

(c) q2 = -6.0 uC

magnitude of force

(in this case both q1 and q2 will attract each other and will move towards each other)
