Two particles of equal mass m go around a circle of radius R under the influence of their mutual gravitational attraction.the speed of each particle with respect to their center of mass will be?? Ans) The Speed will be equal to their velocities in inertial frame itself as there centre of mass will be stationary.
Measurement of Difference in Wavelength of Sodium D1 and D2 Lines: For the measurement of difference in wavelength of two closely spaced sodium lines firstly the M1 is adjusted for
Q. Find the minimum wavelength of X-rays produced by an X-ray tube operating at 1000 kV. λmin = 12400 A 0 / V Therefore λmin = 12400 X 10 -10 / 10 6 = 0.0124 A 0
Q. Explain what do you understand by the terms potential well and potential barrier. How does a particle with energy lesser than the barrier height tunnels through its quantum mech
A charge Q is to be distributed between the objects . what should be the magnitude of the charge on the object so that positive force between the object is maximum?
Q. What is superconductivity? The capability of certain metals their compounds and alloys to conduct electricity with zero resistance at very low temperatures are called superc
Explain natural physics concerned about? Solution: Natural physics is the branch of physics which deals the physics related to nature.For example-physics related to sunlight,re
It is the need of elastic strength of a substance when subjected to repeated stresses and strain. If the substance is reserved undisturbed for some time, the previous properties ar
at what frequancy kinetic energy wil start oscilation
Low frequency loop impedance: Low frequency loop impedance testing is a useful method complementary to DC bonding testing. A visual inspection of cable bundle shields, complem
The thrust developed to propel the jet ski shown in Fig is a result of water pumped through the vehicle and exiting as a high-speed water jet. For the conditions shown in the Fig,
With respect to the center of mass the speed of each particle is (Gm/4R)1/2 as their is no external force acting on the system so velocity of the center of mass is zero velocity of each particle is (Gm/4R)1/2.
