A particle with charge −9 µC is located on
the x-axis at the point 6 cm , and a second
particle with charge 9 µC is placed on the
x-axis at 4 cm .
What is the magnitude of the total electrostatic force on a third particle with charge
2 µC placed on the x-axis at −2 cm ? The
Coulomb constant is 8.9875 × 10^9N · m2/C^2

Question

A particle with charge −9 µC is located on
the x-axis at the point 6 cm , and a second
particle with charge 9 µC is placed on the
x-axis at 4 cm .
What is the magnitude of the total electrostatic force on a third particle with charge
2 µC placed on the x-axis at −2 cm ? The
Coulomb constant is 8.9875 × 10^9N · m2/C^2

anonymous · Answer

sum of the two forces, one due to each point charge.

anonymous · Answer

can you show me I tried it but it wont work for me

anonymous · Answer

what do you have for your two forces?

anonymous · Answer

-1819.97 and 44.94

anonymous · Answer

no, what equations

anonymous · Answer

p1=2uc  p2=9uc p3=-9uc
f1=kp1p2/(.06)^2
f2=kp2p3/(.o2)^2

anonymous · Answer

The radius values should be the distance between the two points (6-(-2))

anonymous · Answer

for the second one?

anonymous · Answer

thx I got it btw can you help me with one more quest?

anonymous · Answer

f2 should be p1p2 not p2p3

anonymous · Answer

sure
