Question

explain how electric field is parallel to force in positive charge and anti parallel to force in negative charge?

Answer 1

No.

2–√2–√=2

2 is rational. 2–√ is irrational.

Even more elementary: if there are no irrational numbers, then it's true by vacuous satisfaction. If there is an irrational number, say x, then note in passing that x is not 0, and 1x is defined (and not 0). Now x1x=1. Can 1x be rational? Since it isn't 0, we then have x=11x which is a (defined) ratio of rational numbers, so x is rational, a contradiction. So both x and 1x are irrational, and their product is 1. You do agree that 1 is rational, don't you?
