Electric Charge and Help Putting an Answer Into CAPA Assignment

[GingerBread27]

I'm using CAPA now for online homework and I seem to be having some trouble inputting an answer. Last semester I used webassign which I think is so much easier. Anyways, the first question was "Two small spheres with charges 7 and 6 coulombs are held 9 m apart. Find the magnitude of the force (in N) between them." I got the answer and it was 4.66E+09 N. Now the second question relates to this one and it says "Is the force attractive (1) or repulsive (-1)? " There are two positive chargers here and same charges are repulsive so I type in repulsive and it was wrong, I put in repulsive force and it was wrong. I even tried typing in attractive and it was wrong. What's going on? Please help! This seems like a ridiculous question to get wrong! Thanks

.It's possible that the answer you're submitting isn't formatted correctly for the system you're using. It could also be that the answer is case-sensitive, so make sure you're entering it with the correct capitalization. If you're still having trouble, contact your instructor or the support staff for the program you're using for help.

It sounds like you are having some trouble with the format of the CAPA assignment. It can definitely be frustrating when you are used to a different platform, but with a little practice, I'm sure you will get the hang of it. As for your specific question about the force being attractive or repulsive, it seems like you have the right idea. Remember that like charges repel each other, so the force between two positive charges would be repulsive. In this case, you may need to enter a numerical value rather than a word. For example, you could try entering a "-1" for repulsive or a "1" for attractive. If that doesn't work, I would recommend reaching out to your instructor or the CAPA support team for further assistance. Good luck with your assignment!
