Apoint charge q1 = 4.00 nc is placed at the origin, and a second point charge q2 = -2.90 nc is placed on the x-axis at x=+ 20.0 cm . a third point charge q3 = 1.95 nc is to be placed on the x-axis between q1 and q2. (take as zero the potential energy of the three charges when they are infinitely far apart.)

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
