What is the electrostatic force between and electron and a proton separated by 0.1 mm? 2.3 × 10^-20n, attractive.
2.3 × 10^-20n, repulsive.
2.3 × 10^-18n, attractive.
2.3 × 10^-18n, repulsive.
2.3 × 10^-16n, attractive.

2.3 × 10⁻²⁰ N, attractive

Explanation:

An electron has a negative charge and a proton has a positive charge. Opposite charges attract each other. We can calculate the magnitude of this attractive force (F) using Coulomb's law.

where,

k: Coulomb's constant

q: charges

r: distance

The modulus of the force is 2.3 × 10⁻²⁰ N.

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff

explanation:

double the distance = divide strength by 4
