What must be the charge on each of two 100 kg spherical masses in order for the electrical force to be equal to the gravitational force?
The electrical force between the two masses is equal to the gravitational force when the magnitude of the electrical force, given by Coulomb's law, is equal to the magnitude of the gravitational force, given by Newton's law of universal gravitation. By setting these equal and solving for charge, you can find that the charges on the two masses must be around 1.45 x 10^17 C each.
Why you couldn't feel the gravitational force and charges can feel the electrostatic force?
But you do feel gravitational force. Your body has weight, doesn't it? Your arms have weight and you feel them being pulled down? If you let go of your arms, they move down? What you feel is the force required to oppose the force of gravity. Newton's Third law says that, for every force, there is an equal and opposite force. Your muscles impose a force holding your arms up. You feel this as effort, i.e. force. As far as electrostatic force, its the same concept...
When you are standing on the ground how much upward force is exerted on you by the earth?
When standing on the ground, the Earth exerts a force equal to your weight in the downward direction (gravitational force) and you exert an equal force in the upward direction on the Earth (reaction force) as per Newton's Third Law of Motion.
What gravitational tension force line of action?
The gravitational tension force acts along the direction of the string or rope that it is exerted through. This force helps maintain the equilibrium of the system by pulling on the objects it is connected to with an equal force in the opposite direction. The line of action of the tension force is always along the string or cable connecting the objects.
The diagram below shows the force exerted on object m1 due to the gravitational attraction between m1 and m2. What is true about the force exerted on m2 due to the gravitational attraction between m1?
The force exerted on m2 due to the gravitational attraction with m1 is equal in magnitude but opposite in direction to the force exerted on m1. This is known as Newton's third law of motion - for every action, there is an equal and opposite reaction.
Do 2 co-orbiting bodies have equal speed?
Only if they have equal masses (in the case of gravitational orbits), or equal electric charges (in the case of electrostatic orbits).
What is the definition of electrostatic equilibrium?
Electrostatic equilibrium simply means that no net force is acting on the charged particle, and it doesn't accelerate, ie it's a charge fixed in space
Does electrostatic force obey newton third law of motion?
Yes, electrostatic force obeys Newton's third law; equal and opposite. Example 1: the electrostatic force on a single Na+ due to a single Cl- in a crystal of NaCl is the same magnitude but opposite in direction. Example 2: the electrostatic force on a single Na+ due to a single SO4^2- in a solution of Na2SO4 is the same magnitude as the force on the SO4^2- but in the opposite direction.
Why is gravitational potential energy equal to kinetic ebergy?
Gravitational potential energy is not equal to kinetic energy:MGY doesn't always equal (1/2)mv2. This holds true in the CHANGE of gravitational potential energy being equal to the CHANGE in kinetic energy because of the Law of Conservation of Energy, Mass, and Charge.

How does the electric charge on the proton compare with the electric charge on the electron?
They are equal in magnitude but opposite in charge.
In a hydrogen atom an electron revolves around a proton Which of these two exerts a greater electrostatic force on the other?
The proton exerts a greater electrostatic force on the electron in a hydrogen atom. This is because the proton has a much larger mass and positive charge compared to the much smaller mass and negative charge of the electron.

Do two objects exert a gravitational force on one another?
The answer to that one is an unqualified 'YES'. There is a pair of equal gravitational forces, one in each direction, between every two specks of mass in the universe, all the time.
What is esu in chemistry?
ESU stands for electromagnetic unit, a unit of electric charge used in the cgs system of units in the field of electrostatics. It is defined as the electromagnetic unit of charge that will impart an electrostatic force of one dyne on an equal charge at a distance of one centimeter.
When you are standing on the ground how much upward force is exerted on you by the earth?
When standing on the ground, the Earth exerts a force equal to your weight in the downward direction (gravitational force) and you exert an equal force in the upward direction on the Earth (reaction force) as per Newton's Third Law of Motion.
Is Franklin is the smallest unit of charge?
No, the Franklin is not the smallest unit of charge. It is a unit of electric charge in the electrostatic system of units, defined as the amount of charge that produces a force of one dyne when placed one centimeter away from an equal charge. The smallest unit of charge is the elementary charge, which is approximately 1.602 x 10^-19 coulombs, representing the charge of a single proton or the negative of that of an electron.
