Answer 2

Option (a), (b), and (c) are correct, because if all the matters were made electrically neutral particles there is no frictional force.

Explanation:

• No force of friction - If all the matters were made of electrically neutral particles such as neutrons, there would be no attraction repulsion between any thing. Then the main reason for the friction force is not there. So there would be no force of friction
• No tension in the string - The solid structure required to produce string couldn't be possible without the frictional force , so without the string there would be no tension.
• No possibility to sit on the chair - Here also the same reason, without frictional force we can't sit on the chair, also there is no possibility to produce the chair structure.
• Earth can move around the sun - The rotation and revolution of the earth around the sun depends upon the Gravitational force , so the earth can move around the sun.

Therefore there would be no friction force, no tension in the string, not possible top sit on a chair if all the matters were made of electrically neutral particles.

Thus the correct answer is Option (a) (b) and (c) .
