What are the four rules of drawing fields?
1 Answer
- 1) Electric field lines are always drawn from High potential to.
- 2) Two electric field lines can never intersect each other.
- 3) The net electric field inside a Conductor is Zero.
- 4) Electric field line from a positive charge is drawn radially outwards and from a negative charge radially inwards.
Does electricity affect gravity?
Electric current travels by the movement of electrons. As electrons are mass particles, therefore, gravity has a minute effect on their movement. Since electricity runs at speed comparable to the speed of light, the effect of gravity on electricity would be the same as that on traveling light.
Is artificial gravity theoretically possible?
Speculative or fictional mechanisms. In science fiction, artificial gravity (or cancellation of gravity) or “paragravity” is sometimes present in spacecraft that are neither rotating nor accelerating. At present, there is no confirmed technique that can simulate gravity other than actual mass or acceleration.
Why don’t you feel the electric force on you all the time?
gravitational force. Why don’t you feel the electrical forces that act on you all the time? Both repelling and attracting forces act on you, and the forces cancel each other out.
Why is electrostatic force attractive or repulsive?
If two charges have the same sign, the electrostatic force between them is repulsive; if they have different sign, the force between them is attractive.
How strong is electrostatic force?
Even though electrostatically induced forces seem to be rather weak, some electrostatic forces such as the one between an electron and a proton, that together make up a hydrogen atom, is about 36 orders of magnitude stronger than the gravitational force acting between them.
Why electrostatic force is a non-contact force?
Electrostatic forces are non-contact forces; they pull or push on objects without touching them. Rubbing some materials together can result in something called ‘charge’ being moved from one surface to the other. Charged objects pull on other uncharged objects and may either push or pull on other charged objects.
