Why are sharp projections avoided in machines?
At the sharp projection of a charged body the charge density becomes very high. Due to which the air molecules which come in contact with such projection become ionised or broken down into free electrons and positive air Ions. Then similar charges are repelled away by the tips whereas the opposite charges go towards the tip and get attracted by the tip. These opposite charges reduce the no. of charges present on the tip. he process continuously takes place and charge present on the tip continuously goes on decreasing.
Why are smart pretty girls attracted to you and crush on you for years?
this is because when girls are smart and pretty every 2nd guy likes them and that what makes them popular and guys get attracted towards 'em....!
Is hemoglobin attracted towards magnet?
No, hemoglobin is not attracted to magnets. Hemoglobin is a protein found in red blood cells that carries oxygen, and it does not contain any magnetic properties.
What would the North Pole of magnet be attracted to?
South Pole of another Magnet or towards the South Pole of the Earth
What are the factors that affect for deflection of cathode rays towards magnetic and electric field?
The electron is a charged particle and can be attracted and repelled by a magnetic field. In a CRT the magnetic field is generated by coils around the neck of the tube. A voltage applied to the coils,will turn them into electromagnets. The coils are supplied with a varying voltage from electronic circuits. The waveform is usually a 'sawtooth', which rises slowly and then returns to '0' rapidly. This will cause the electron beam to move across the screen and then return back to the beginning. Two sets of coils are provided horizontally and vertically. This arrangement allows for the beam to scan across the screen, producing lines, moving progressively downward, making a field.
How a charged rod placed near an uncharged metal object can repel?
Charged rod and an uncharged metal object attract each other because free electrons in metal are either attracted or repelled by the charged rod. If the rod is positively charged then free electrons are attracted towards it and both objects attract each other. If the rod is negatively charged then free electrons are repelled by it and positive ions are attracted by the rod and both objects attract each other.
Why electrons move in electricity?
Electrons will move in response to an electric potential - also known as a voltage. The electron will be attracted towards, or repelled from, one direction, due to this voltage.
How do they get the electrons moving?
to actually get the electrons moving there needs to be an electric potential better known as voltage. the voltage allows the electrons to be attracted towards, repelled from in one direction across cables
Does current always go from positive to negative?
We call this Conventional Current Flow, where imaginary positively charged particles are repelled away from a positive charge and attracted towards a negative charge.The reality is that electrons are actually flowing through the conductor. Electrons are negatively charged particles and flow from negative to positive. It's just easier to think of a positive current flowing than a negative current.
Why is an alpha particle attracted to a negative plate?
Alpha particles are deflected towards negative plates because they are positively charged.
When a atom losses a electron it becomes what kind of ion?
A cation. A positively charged ion that is attracted towards the cathode in an electrolytic cell.
Are electrons negatively charged or is it just a convention then how do tell it is attracted towards the positive?
electrons have a negative charge...or atleast that's what i was taught:P
Is plastic ruler gets attracted towards pieces of paper when rubbed with oily hair?
when rubbed with hair, ruler acquires some charge due to static electricity...becomes charged body and attracts tiny pieces of paper towards it.
Why neutral bodies attract positively charged bodies?
no
Why hairs are attracted towards the CRT monitor when it is on?
Static electricity. The flow of electrons charges the screen (the phosphor dots on the monitor glow because electrons are accelerated towards the screen).Hair is a protein complex that insulates (electrically as well).The static electric charges on (especially dry) hair are attracted to the charged screen surface.
Are molecules attracted towards each other by gravity?
They better be! Electrical forces are much stronger than gravitational (for the same charged mass).
Charging by friction eg?
When we rub the hair with a comb then charges could be produced on the comb. When this comb is taken near by a bit of paper then that piece would be attracted towards the charged comb.
