What is the number of electric lines of force that radiate outwards one Coulomb of charge in vacuum?

≅ 7.5 x 10^{9} [ ans.]

What is the number of electric field lines coming out of 1 Coulomb positive charge?

1.13*10^12.

What do you call the total number of electric lines of force in an electric field?

Electric flux
Electric flux: The number of electric field lines passing through a surface area normally is called electric flux. It is denoted by Φ.

How do you find the number of electric field lines?

(See Figure 2.) The electric field strength is exactly proportional to the number of field lines per unit area, since the magnitude of the electric field for a point charge is E=k|Q|r2 E = k | Q | r 2 and area is proportional to r2.

What is the number of electric lines of force emerging?

Hint: The number of electric field lines of force emerging out of a closed surface represents the flux and we need to find the charge enclosed. The Gauss law of electrostatics relates the amount of charge enclosed with flux, so it is ideal to use the Gauss law in this case.

What is electric lines of force in physics?

An electric line of force is an imaginary continuous line or curve drawn in an electric field such that tangent to it at any point gives the direction of the electric force at that point. the direction of a line of force is the direction along which a small free positive charge will move along the line.

What are electric lines of force 12?

An electric line of force is an imaginary curve drawn in such a way that tangent to this curve at any point gives the direction of the electric field at that point. It can be a path with maybe a curve or a straight line.

What does number of field lines mean?

When the field is stronger, the field lines are closer to each other. The number of field lines depends on the charge. The field lines should never crossover. Electric field and electric field line are tangent at the point where they pass through.
