Answer #1

In the figure, the particles have charges q1
= -q2 = 150 nC and q3 =
-q4 = 91 nC, and distance a = 3.9 cm.
What are the (a) x and
(b) y components of the net electrostatic
force on particle 3?

Three charged particles form a triangle: particle 1 with charge
Q1 = 108.0 nC is at xy coordinates (0, 4.30 mm), particle 2 with
charge Q2 is at (0, -4.30 mm), and particle 3 with charge q = 44.0
nC is at (4.60 mm, 0). What are (a) the x component and (b) the y
component of electrostatic force on particle 3 due to the other two
particles if Q2 is equal to 108.0 nC? What are (c) the x...

Part A) Two particles with positive charges q1 and
q2 are separated by a distance s.
Along the line connecting the two charges, at what distance from
the charge q1 is the total electric field from the two charges
zero?
Express your answer in terms of some or all of the
variables s,
q1,
q2 and
k =14πϵ0. If
your answer is difficult to enter, consider simplifying it, as it
can be made relatively simple with some work.
Part B)...

Three charges, q1 = 9.0 nC, q2 = 5.0 nC, and q3 = –3.0 nC are
arranged in a right angle triangle as shown in the diagram. The
distance between q1 and q2 is r12 = 6.0 cm, and the distance
between q2 and q3 is r23 = 3.0 cm. Positive x is taken to the right
and positive y is taken upward.
I can not upload the graph so q2 at (0,0) q1 at (-6,0) q3 at
(0,-3)
