Since, F = 9 x 109 q1q2/r2
Then , substituting the value of q1 , q2 and r2 ,we get ,F = 5 x 3 /42 = 0.9375 Newton

What is the difference between an ampere and a coulomb?
A ampere is a measure of the flow rate of electricity a coulomb is an amount of electricity. So 1 ampere is a flow of electricity at the rate of 1 coulomb per second.AnswerStrictly speaking, as the ampere is an SI base unit whereas a coulomb is a derived unit, it is more accurate to say that 'a coulomb is an ampere second (A.s)'.With reference to the first answer, the ampere is the SI unit for electric current (not the 'flow rate of electricity', which is meaningless), and the coulomb is the SI unit for electric charge (not the 'amount of electricity'). 'Electricity' isn't a quantity, so it cannot be measured.
The equation of coulomb's law?
developed in the 1780s by French physicist Charles Augustin de Coulomb The magnitude of the electrostatic force between two point electric charges is directly proportional to the product of the magnitudes of each charge and inversely proportional to the square of the distance between the charges. F = k q1q2 \ d2 As F is electric force k is coulomb's constant = 9*10^9 Nm^2\C^2 q1 and q2 are the charges measured in coulombs d is the distance between them measured in meters
What happens when some charge is placed on a soap bubble?
its radius increases
How many water stations will be needed if water stations will be placed every 600 meters of a fifteen kilometers race?
Water station will be placed every 400 meters of a 5-kilometer race. How many water stations are needed?
Why do you seldom see any effects from the strong interactions that can occur between charges?
Because most of the time, the objects concerned are electrically neutral or bear only a small net electric charge, making other interactions such as gravity the dominant interaction. For example, an electrically charged ball will fall to the ground most of the time, even if placed beneath another object bearing the opposite charge, because the ball would have to be very light and very stronly charged in order to make the electrical Coulomb interaction strong enogh to become comparable to the gravitational force exerted on the ball by the earth's mass. In some cases however, such as a single electron flying through the electric field of a capacitor, the charge of the particle with respect to its mass is so big that gravity is neglectable compared to the Coulomb interaction.
What is the charge between 1 colomb placed at a distance 1 meter of another 1 colomb of charge?
The charge is 1 coulomb and 1 coulomb, respectively.
What is a colulomb?
Coulomb is the unit of electric charge is SI system of units. One coulomb is that charge which when placed from a similar charge in free space at a distance of one meter would repel with a force of 9 x 109 N
How many proton in a coulomb?
One coulomb is equal to the force of repulsion when a unit positive charge is placed from a similar charge at a distance of 1m.
What is the voltage at the location of a Coulomb charge that has an electric potential?
A positive test charge of 1.6 x 10-11 C is placed in an electric field The force acting on it is 3.2 x 10-4 N What is the magnitude of the electric field intensity at the point where the charge is placed
How can you find the force acting on a charge of x coulombs in an electric field of y micro coulomb?
First we must know where the charge x coulomb has been placed. Without that data we cannot find the required. Field due to y micro coulomb at a point distance r will be 9x109 y / r2 micro newton So the force on x coulomb kept at that point will be 9x109 xy / r2 micro newton
When 40 nC of charge are placed on a conductor the potential is 8 V. What is the capacitance?
The capacitance is defined as charge divided by voltage, so all you need to do is divide the 40 times 10 to the power -9 Coulomb by the 8 V.
How do you find the magnitude of the force between two protons?
Experiments have shown that the electric force between two objects is proportional to the inverse square of the distance between the two objects. The electric force between two electrons is the same as the electric force between two protons when they are placed as the same distance. This implies that the electric force does not depend on the mass of the particle. Instead, it depends on a new quantity: the electric charge. The unit of electric charge q is the Coulomb (C). The electric charge can be negative, zero, or positive. The electric charge of electrons, protons and neutrons are -1.6 x 10-19, 1.6 x 10-19, and 0. Detailed measurements have shown that the magnitude of the charge of the proton is exactly equal to the magnitude of the charge of the electron. Since atoms are neutral, the number of electrons must be equal to the number of protons. The precise magnitude of the electric force that a charged particle exerts on another is given by Coulomb's law.
What is the force between two charge particle when medium is placed between them?
electrostatic force, which acts between two charged particles placed certain distance apart in a medium.

Whose descendants were placed in charge of the Temple?
Aaron's descendants were placed in charge of the temple.
What is in potential?
A little complicated, but here are two examples: In electric fields, a potential of 5 Volts means that if a 1 coulomb charge were placed there, it would have a potential energy of 5 Joules. In gravitational field, a potential of 5 J/kg means that if a 1 kilogram mass were placed there, it would have a potential energy of 5 Joules.
What does an ammmeter measure when it is placed between two cells?
How many coulombs of electrons go through it each second. A coulomb is 6.23X10^18 electrons.
