He compared is to B) Isaac Newton
Isaac Newton has earlier on came up with his formula on gravitation as;
F = GMm/r²
Later on Charles Coulomb came up with his formula on electrostatic force as:
F = kQq/r²
You can see his formula is similar to that earlier formulated by Isaac Newton on gravitation.
Answer:
55N
Explanation:
Using Newton's second law of motion:
F=ma
Force=mass × acceleration
F=25×2.2
F=55N
So 55 Newtons are needed
