What is the gravitational force between electron and proton?
The mass of an electron is 9.10938188 × 10-31 kg; the mass of a proton, 1.67262158 × 10-27 kg. The gravitational attraction then is 1.0167349 × 10-49 N, according to the law of gravitation.
Do electrons and protons exert a gravitational attraction on each other?
Both electrons and protons have mass, so it is easy to conclude that they exert a gravitational pull on each other.
How do electrons and protons exert forces on each other?
Charges exert Force So electrons are attracted to protons and this is what holds atoms together. A force that pushes apart particles is a repulsive force. Force of attraction exists between oppositely charged particles – electrons and protons are therefore attracted to each other.
Do electrons exert gravitational force?
“Yes. All mass and energy has gravitational effects. For an electron, as with a proton, this effect is unimaginably small.
What is the ratio of the electric force to the gravitational force?
The ratio of the magnitude of the electrostatic force to gravitational force in this case is, thus, FFG=2.27×1039 F F G = 2.27 × 10 39 .
Do protons exert gravitational force?
If you take two protons and hold them very close together, they will exert several forces on each other. Because they both have mass, the two protons exert gravitational attraction on each other. Also, they both have internal “color” charge and thus exert attraction via the strong nuclear force.
What is the ratio of gravitational force and electric force between two electron one point?
The ratio of electromagnetic and gravitational forces between two electrons is nearly, ( Charge of the electron e=1. 6×10−19C, mass of the electron m=9. 1×10−31kg, permittivity of free space 4πε01=9×109 Nm2C−2, universal gravitational constant G=6. 67×10−11Nm2kg−2 )
How much is the electrostatic force stronger than the gravitational force for an electron and proton?
So, the electric force is 1039 times stronger; gravity seems negligible in comparison!
What is the ratio of the magnitude of electrostatic force and gravitational force between an electron and a proton?
1.10 FFG=2. 27×1039. This is a remarkably large ratio! Note that this will be the ratio of electrostatic force to gravitational force for an electron and a proton at any distance, taking the ratio before entering numerical values shows that the distance cancels.
