Electric field intensity is the strength of an electric field at any point. It is equal to the electric force per unit charge experienced by a test charge placed at that point, or E = F q From Gauss law, considering a spherical surface with charge at its center as Gaussian surface,
$$\textbf{Step 1: Define electric field intensity}$$ The electric field intensity at any point is the force experienced by a unit positive charge placed at that point. $$\vec{E} = \dfrac{\vec{F}}{q_0}$$
Define intensity of electric field and write its unit. Solution. Verified by Toppr. The intensity of electric field at a point is defined as the electric force experienced by the test charge qo placed at that point. Mathematically, electric field strength is given by E = F qo= kq r2. Unit of electric field strength is Newton/Coulomb.
Solution. (a) The magnetization of a material may be defined as the net magnetic moment per unit volume of the material. (b) The magnetic intensity (H) is defined as the product of the number of turns per unit length in a coil (n) and the current that it carries (I). Its S.I. unit is A/m. Hence, H =nI.
In Longitudinal Position. +/-m = Magnitude of the south and north poles. r = Distance of point P from the center of the magnet. l = Length of the bar magnet. ∴ Intensity of the magnetic field at point P is given by, where M is the magnetic moment = 2*m*l. Case: For a small magnet, r 2 ≫ l 2.
Solution. Verified by Toppr. Gravitational intensity is a vector quantity related to the condition at any point under gravitational influence the measure of which is the gravitational force exerted upon a unit mass placed at the point in question. It is denoted by g.
Q 1. Define intensity of radiation on the basis of photon picture of light. Write its S.I. unit. View Solution. Q 2. (a) Why photoelectric effect cannot be explained on the basis of wave nature of light? Give reasons. (b) Write the basis features of photon picture of electron magnetic radiation on which Einstein's photoelectric equation is based.
The intensity of perception of a sound by the ear also depends on the distance from the sound source. Intensity also depends on the nature of the elastic medium between the source of a sound and the ear. Non-elastic media, like wool, felt, etc., weaken the sounds. The formula for sound Intensity: It is defined mathematically as:
The electric field intensity is the measure of the strength of an electric field at any point. It is equal to the electric force per unit charge experienced by a test charge which is placed at that point. The electric field intensity between two points is the vector sum of all the electric fields acting at that point.
