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.
The image of a candle is produced by a convex lens on a screen. The lower half of the lens is painted black to make it completely opaque. Illustrate the ray diagram to show the ima
Shell type transformers . In this type of transformer the iron core surrounds the copper windings. The core is in the shape of numeral 8. The entire flux passes by the central pa
Start from the expression of the electric field outside an infinite sheet of uniform surface charge density, E = s/2epsilon, derive the electric field just outside an ideal conduct
Q When calculate Planck's constant, a student's calculations produce values of 5.78 × 10 -34 J·s and 7.29 × 10 -34 J·s. If the accepted value is 6.63 × 10 -34 J·s, what is
The waves which needs medium for their propagation are known as mechanical waves. Example : Waves on string and spring, waves on water surface, sound waves, seismic waves.

The minimum real charge on any particle which can exist is: (1)1.6x 10 -19 coulomb (2) 1.6x 10 -10 coulomb (3)4.8 x 10 -10 coulomb (4)Zero Ans: (1)1.6x 10 -19 c
For a very every case the moment of inertia of a one particle about an axis is given by, I = mr 2 Here, m is the mass of the particle and r its distance from the axis under
Who are the best system integrators? Being fairly the opposite of fiber optics manufacturers, system producers are generally small companies. In this case size has the opposite
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.
