## How do you find the minimum force between two charges?

We know that, F=(1/4πε0)(q^1q^2)/r^2. F will be minimum when q1andq2 are minimum i. e. q1=q2=1.6×10−19. Then, Fmin=9×10^9N×(1.6×10^−10)^2.

## What is minimum possible force between?

Answer: Newtons (approx.) Explanation: According to Coulomb’s law, the force is minimum if both the charges are minimum, when the charges are kept at a fixed distance apart. Thus, the minimum possible Coulombic force should be that between two electrons when kept 1 meter apart.

## What is the minimum electrostatic force?

Answer:10^-28N. Minimum possible charge is charge of electron.

## What is the minimum value of force acting between two point charges?

E=F/q2; hence it can be seen that electric field is 0 only when either force between them is zero or the charge which produces the electric field is zero.

10−19N.

## When the distance between two charges is halved What is the force between them?

The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Hence, if distance between charges is halved (charges remaining kept constant), the force between the two charges is quadrupled.

## How does the electric force between two charged particles change if the distance between them?

Like charges repel each other; unlike charges attract. … The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value.

## What is the ratio of electrostatic and gravitational force between two protons?

This is also an attractive force, although it is traditionally shown as positive since gravitational force is always attractive. 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 .

## What is the minimum charge on a particle * 1 point?

The minimum charge that a particle can have is the 1.6×1019 coulomb. A given particle cannot have a charge lower than this.

## What is the lower limit of the electric force between two charged particles placed at a separation of 1 cm in vacuum?

The smallest possible charge would be that of an electron. Thus, Hence, lower limit to the electric force between two particles placed at a separation of 1 cm would be 2.3× 1024 N.

## What does electric field depend on?

The strength of the electric field depends on the source charge, not on the test charge. … Because an electric field has both magnitude and direction, the direction of the force on a positive charge is chosen arbitrarily as the direction of the electric field.

## What is electric field due to a system of charge?

The electric field due to a given electric charge Q is defined as the space around the charge in which electrostatic force of attraction or repulsion due to the charge Q can be experienced by another charge q.

## What will the value of electric field at the Centre of electric dipole?

Answer: Twice the electric field.

## What is the potential energy of the equal positive point charges of 1 Microcoulomb is held 1 Metre apart in air?

∴ U = 9 mJ. Hence, the Potential energy of the Equal positive charges of 1 micro coulomb each held 1 m apart in air is 9 mJ.

## What will be the value of electric field at the Centre of dipole?

Zero. B. Equal to the electric field due to one charge at the centre.
