Which is the weakest force?
Think it through first, then pick an option.
- a Gravitational force
- b Electromagnetic force
- c Strong nuclear force
- d Weak nuclear force
Answer and explanation
Correct answer: a Gravitational force
Gravity is the weakest of the four; the small charge on a comb beats the pull of the whole earth.
Why the other options are wrong
- b Electromagnetic force: The electromagnetic force is 10³⁶ times stronger than gravity, so it is not the weakest.
- c Strong nuclear force: The strong nuclear force is the strongest force of the universe.
- d Weak nuclear force: Despite its name, the weak nuclear force is much stronger than gravity.
