Question

1. Pick two objects in your room. Physics could describe the gravitational attraction between them or the

electric force between them – why is neither one big enough to have noticeable effect?

2.If you double the distance between two charges, what happens to the electric force between them?

Answer 1

1. For gravitatio₂n²al force of attraction between any two objects in our room, universal gravitational constant G is very low, of the order of 10^-11 so this force goes unnoticed. On the other hand, for electrostatic force between two objects in our room, normally charge over the objects is very low, of the order of micro Coulomb (10^-6) each so again, this force goes unnoticed

2. Electrostatic force between two charged bodies is given as F = kq​^​_​​​1​​​​q_​​​2​​ /r^​​2 so on doubling the distance between two charged bodies, force will become one fourth.
