# Electrostatic Forces and Movement of Charged Particles

Please show all work and diagrams plus equations used to solve problem. Thanks!

1) Particles 1, with charge q1 and 2, with a charge q2 are on the x axis, with particle 1 at x = a with and particle 2 at x=-2a. For the net force on a third charges particle, at the origin to be zero q1 and q2 must be related by q2=:

(answer B, but explain)

a) 2q1

b) 4q1

c) -2q1

d) -4q1

e) -q1/4

2) A particle with charge Q is on the y axis a distance a from the origin and a particle with charge q is on the x axis a distance d from the origin. The value of d for which the x component of the force on the second particle is the greatest is:

(e is answer - why)

a) 0

b) a

c) SQRT 2a

d) a/2

e) a/ SQRT 2
