The diagram represents two small, charged, identical metal spheres, A and B, that are separated by a distance of 2.0 meters. If the two spheres were touched together and then separated, the charge on sphere A would be *
q1= -1.6x10^-6C
q2=+1.0x10^-6 C
d=2m
Final answer is -3.0x10^-7 C, but I don't know why it is like that.

if you are trying to figure out if it is right. I believe it is right (the answer) but trust your instincts go for it.

Explanation:

he’s right the answer is -3.0*10^-7 C

Explanation: i just did it lol

to be honest as much as i would love to answer this. i feel as if something's missing. just saying.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
