Question

Pick the correct option - If all matter were made of electrically neutral particles such as neutrons,

• A. there would be no force of friction
• B. there would be no tension in the string.
• C. it would not be possible to sit on a chair.
• D. the earth would not move around the sun.

Answer 1

Answer: (A), (B), (C)

The correct options are
A

there would be no force of friction

B

there would be no tension in the string.

C

it would not be possible to sit on a chair.

Oh Wow!!!

Wonderful Question

So everything is made of just neutrons which are neutral - no charge, no repulsion. No electromagnetic force.

Let's check each option

(a) Force of Friction.

Well friction is electromagnetic in nature. We saw the guy with the weird haircut and the crooked nose talk about it so that's out of the picture.

(b) Tension

Tension is also electromagnetic. The atoms in a taut string attract to build tension and keep the string together. So that's also gone.

(c) Sitting on a chair.

When we sit, our heavy weight is balanced by the normal force given by the chair, which is also electromagnetic in nature. So sadly we are doomed to stand. Wait will that be possible?

(d) Earth's Revolution.

Well that I know happens because of gravitational pull. So there is no way for that to be affected
