Homework Statement
the particles have charges q1 = -q2 = 296 nC and q3 = -q4 = 198 nC, and distance between each particle is 5.5cm.
Homework Equations
Find the net electrostatic force on particle 3
::Answer is required in vector form <x,y,z>::
The Attempt at a Solution
Using Coulombs law to find the fnet of each particle.
i.e.
eq1 = [(9e9) * 1.98e-7 * 2.96e-7] / .055^2 = force on particle 3 by q2 in x and y direction AND q1 in y direction
eq2 = [(9e9) * 1.98e-7 * 1.98e-7] / .055^2 = force on particle 3 by q4 in x direction
Then adding the forces together, applying the fact that q 1 and q3 repel each other (negative force)
getting <eq1+eq2, eq2-eq1>
