Question

What is the force, in terms of Coulomb's constant, between two electrical charges of `-45 C` and `-75 C` that are `15 m` apart?

Answer 1

`F=135*10^9 N`

Explanation:

`"The Coulomb's law is given by formula :" F=k*(q_1*q_2)/d^2`
`q_1,q_2:" charges"`
`d:" distance between charges"`
`k=9*10^9" "(N*m^2)/C^2 " Coulomb's constant"`
`F=9*10^9((-45)*(-75))/15^2`
`F=135*10^9 N`
