If the charges are situated in a medium of permittivity ε, then the magnitude of the force between them will be, If the charges are situated in a medium of permittivity ε, then the magnitude of the force between them will be,
Fm = 1/4∏€ X q1q2/r2 -------------------------------------(2)
Dividing equations 1 and 2 we get F/Fm = € / €0 = € r. This ratio is called as relative permittivity or dielectric constant. This is equal to 1 in air. Hence the force between two charges depends on the medium in which they are situated.
A particle is projected from ground with velocity 40sqrt2m/s.find- a)velocity and b)displacement of particle after 2sec .Take g=10m/s^2 Ans) velocity v=u+at a=-g v=40√2-10*2
A passenger sitting in the rear of a bus claims that she was injured as the driver slammed on the breaks, causing a suitcase to come flying towards he from the front of the bus. If
Neutron is a fundamental particle carrying: (1)A charge of +1 unit and a mass of 1 unit (2)No charge and a mass of 1 unit (3)No charge and no mass (4) A charg of -1
For higher current rating application, resistance wires with extremely large cross sections are required. The necessary large cross sections are produced in the form of resistance
Is there a way that you can gain potential energy and release kentic energy in Volleyball?
The signal which shows the continuous variation of voltage with time is called as analog voltage signal
Why diffraction can't occur if slit width is less than the wavelength of the light? Can you explain?
1. A screw gauge consists of U- shaped metallic frame F. To one end of this frame, a flat shaft is fixed. On the opposite end of a hollow long cylinder C is fixed. 2. The hollow c
