What is the gravitational force of attraction between two bodies of ordinary masses not notisable in every day?
It is F= (mass of one object)(mass of second object)(Gravitational constant)/(the distance between them)2 The gravitational constant is about 6.67x10-11 The mass should be in kg, and the distance in meters
What did Newton say about how the distance between two bodies affects gravity?
Newton said that the gravitational attraction between two objects is directly proportional to the product of the two masses and inversely proportional to distance squared. Gravitational attraction between masses A and B = constant x mass A x mass B / distance2
What is the relationship between magnetic attractive force and distance?
they are inversely related. as the distance increases the magnetic attraction decreases and when the distance decreases the magnetic attraction increases.
What two factors does the strength of gravity depend on?
The masses, and the distance. The formula for gravitional attraction is: F = G m(1) m(2) / r2, where G is a constant, m(1) and m(2) are the two masses, and r is the distance.

What are the factor affecting capacitances of capacitance?
The area of the sheets, the distance between them, and the material between them.
What is magnetic permeability of materials?
Relative permittivity or dielectric constant of a medium is defined as the ratio of force between two charges separated by a certain distance in air or vacuum to the force between the same charges separated by the same distance in the medium.According to American Heritage Dictionary:permittivitySYLLABICATION: per·mit·tiv·i·tyPRONUNCIATION: PERM eh TIV eh TEENOUN: Inflected forms: pl. per·mit·tiv·i·tiesA measure of the ability of a material to resist the formation of an electric field within it. Also called dielectric constant, relative permittivity.
What is dielectric constant?
A dielectric is an insulating material that does not conduct electricity and is transparent to an electromagnetic field. Dielectric materials are used to separate conducting surfaces such as the plates inside a capacitor, wires inside transformers, electric cable conductors, and elsewhere in the electric industry where electrical separation of charged elements is necessary. The dielectric constant is a ratio of the capacitance of a capacitor in which a particular insulating material is the dielectric, to the capacitance of the capacitor in which a vacuum is the dielectric.
If the distance between the parallel plate capacitor is reduced to half and a dielectric of dielectric constant k is introduced then how does electric field varies?
From the formula, E = V/d, where V is the voltage and d is the distance, it can be seen that the electric field and the distance are inversely related. Thus, as the distance between the parallel plate capacitors is reduced to half, the electric field is increased twice. Moreover, is a dielectric constant k is introduced, the capacitance will increase. This direct relationship can be seen in the formula, C = [k(Єo)A]/d, where k is the dielectric constant. The lowest possible value of k is 1; and that is when the dielectric is a vacuum. Other dielectric constants are greater than 1, such as teflon which has a dielectric value of 2.1 As the capacitance increases, the electric field also increases. (E = 1/2(CV^2))
What is the capacitance of a parallel plate capacitor with a dielectric of oil-soaked paper The dielectric constant is 3.8 the distance between the plates is 0.00625 inches and the plate area is 0.25?
3.42*10^-11 farad.
What 4pie refers to in force constant in coloumbs law?
it refers to the inverse of the force between two point charges separated through unit distance.

What does universal gravitational constant means?
The force of gravitational attraction between any two bodies, F, is given by the equation:F = G*M1*M2/r2 where M1 and M2 are the masses of the two bodies, r is the distance between their centres of mass and G is the universal gravitational constant.
How does distance affect gravitional attraction of two objects?
For every doubling of distance, the "force of attraction" is reduced by a factor of four. For every halving of distance, the "force of attraction" is increased by a factor of four.
How to find capacitance of two parallel plates?
You can compute it from the area of the plates, the distance between them, and the dielectric constant of whatever is between them. I'll leave it up to you to lookup the equation (or derive it if you want to get ambitious, it really isn't too hard) and find a published table of dielectric constants.
What is the gravitational attraction between mars moons?
It greatly depends upon their distance to one another at the time. However, the universal law of gravitational attraction applies: F = G * ((m1*m2)/r) where m1 is the mass of moon 1 (kg) m2 is the mass of moon 2 (kg) r is the distance (m) G is the gravitational constant F is the force of attraction.
What did Newton say about how the distance between two bodies affects gravity?
Newton said that the gravitational attraction between two objects is directly proportional to the product of the two masses and inversely proportional to distance squared. Gravitational attraction between masses A and B = constant x mass A x mass B / distance2
