How many times electrical force is greater than gravitational force?
The electric force between these electrons is 2.40 x 1043 times bigger than the gravitational force. In other words, electricity is almost a trillion-trillion-trillion-trillion-trillion times stronger than gravity.
What is the ratio of electric force and gravitational force between a proton and electron?
1)Compute the ratio of gravitational force and electrostatic force between an electron (mass- 9.1 × 10^-19 kg )and a proton (mass- . 1.7×10^-27 kg). GIVEN: e=1.6 ×10^-19C. G=6.67 ×10^-11 N m^2 /kg^-2.
What is the ratio of the electric force to the gravitational force between two electrons?
4.17×1042
Hence, the ratio of electric to gravitational force between two electrons is 4.17×1042.
What is the gravitational force between these two protons?
Example 2.1: Use Newton’s Law of Gravitation to calculate the gravitational attraction between two protons separated by a distance of 1 fm (i.e. 10-15 m). This problem involves a simple substitution: F = Gmpmp/r2 = [6.67 x 10-11] [1.67 x 10-27]2 / [1 x 10-15]2 = 1.86 x 10-34 N.
Are electrical forces stronger than gravitational?
Even though these equations are very similar, the constants k and G show you that the electric force is much stronger than the gravitational force. In addition, while gravitational forces are always attractive, electric forces can either be attractive or repulsive, depending on the nature of the charges.
Why is electrical force stronger than gravitational?
Gravitational force is proportional to the masses of interacting objects, and the electrostatic force is proportional to the magnitudes of the charges of interacting objects. For electrons (or protons), electrostatic force is dominant and is much greater than the gravitational force.
What is the force between a proton and an electron?
Hence, the electrostatic force of attraction between a proton and an electron in a hydrogen atom is $9.216 \times {10^{ – 8}}{\text{ N}}$ . Note: Although the magnitude of the charge on an electron and a proton is the same but their signs are opposite of each other.
What is the ratio of electrical and gravitational force between proton and electron in a hydrogen atom?
The electron carries the elementary charge: q = -e, 1.602 x 10^-19 C, and the proton carries the same charge but positive q = +e. F = -8.239 x 10^-8 N (- indicates attraction). The ratio E/G = 2.268 x 10^39.
How do you find the gravitational force between two electrons?
The gravitational attraction between two electrons is given by Gm2/r2, where G is the gravitational constant, m is the electron mass and r is the distance between the two electrons.
What is the magnitude of the electric force between an electron and a proton in a hydrogen atom?
The electric force is sufficient to keep the electron in “orbit” around the proton in the hydrogen atom. At 39 orders of magnitude smaller, the gravitational force might as well be zero….solution.
