physics. Can you check my answer?
posted by Jordan on .
Two spherical objects are separated by a distance of 2.41 x 103 m. The objects are initially electrically neutral and are very small compared to the distance between them. Each object acquires the same negative charge due to the addition of electrons. As a result, each object experiences an electrostatic force that has a magnitude of 4.18 x 1021 N. How many electrons did it take to produce the charge on one of the objects?
This is the work that I did....
I first found that Q= 1.64 x 10 ^ 18.
I then divided by e.
The answer I got was 10.23, but I am being told that is wrong.

who told you it was the wrong answer?

I submitted it online and I was told it was wrong. I also tried 10.22 and 10.24 to see if there was a rounding error.

I just realized that the answer had to be 10. Im sorry for any confusion. Thank you for your help though.
