"some elements have only one stable isotope"
Explanation:
there ya go! Pls give me brainliest!
Answer: a) 8.2 * 10^-8 N or 82 nN and b) is repulsive
Explanation: To solve this problem we have to use the Coulomb force for two point charged, it is given by:
Replacing the dat we obtain F=82 nN.
The force is repulsive because the points charged have the same sign.
Answer:
aww that's simple! its B can i get brainliest? i really need some points rn <3
