State 'Inverse square law of magnetism'.
A. Coulomb's inverse law of magnetism states that, "The force of attraction or repulsion between two magnetic poles is directly proportional to the product of their pole strengths and inversely proportional to the square of the distance between them and acts along the line joining the poles"
F ∝ m1m2
F ∝ r2
F = K m1m2 \r2
An x-ray photon collides with a free electron, and the photon is scattered. During this collision there is conservation of: a) Momentum but not energy b) Neither momentu
#questi1. A sound with a frequency of 261.6 Hz travels through water at a speed of 1435 m/s. What is the wavelength of the wave? a. 1.83 x 10 -1 m b. 3.753 x 10 5 m c. 5.486 m
what is space charge and diffusin capacitance.
BH curve: For any ferromagnetic material there is a definite value of flux density (B), corresponding to a specified value of magnetising force (H). These values can be ascert
An electron has momentum that is 90 % larger than its classical momentum. Find speed of electron. Classical momentum Relativistic momentum Here m is effective mass Given, Spe
The loudness of sound depends on: Amplitude of vibration. Area of vibrating body. Distance from the sounding body. Density of the medium.
Q. State Brewster's law. Brewster's law the digression of the polarising angle is numerically equal to the refractive index of the medium. That is tan ip = μ
How noisy is an illuminator? It is very noisy, slightly so or completely silent, depending upon the power source and the construction. There heat dissipation is something which
Characteristics of resistance:- Similar amount of current passed by each resistance i.e. I = I1 = I2 = I3 = I4 ........ The sum of potential difference across individual res
