Answer True or False to each case. Coulomb's law states that the force between static charges Q1 and Q2

Question

is proportional to Q1 Q2.

is proportional to the total charge Q1+Q2.

is K Q1Q2/r where K is a universal constant.

is proportional to 1/r2.

is a force of attraction.

Answer 1

k Q1 Q2 / r^2

note r^2 not r

so
1. yes
2 no
3 no
4 yes if you mean 1/r^2
5 not necessarily, Like charges repel.
