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.
Coulomb; C (after C. de Coulomb, 1736-1806) The derived SI unit of electric charge, described as the amount of charge transferred through a current of 1 A within a period of 1
Q. Illustrate about Optical Memories? In 1983 one of the most successful consumer products of all times was introduced which is compact disk (CD) digital audio system. This CD
A 50 newton light fixture is supported by two guy wires as shown. Determine the tension in each wire
Electric Current: Electric current may be described as the rate of flow of charge. I=q/T Where, I = electric current q = charge T = time The unit of current i
what is plane diffraction grating?

Sample of ethane gas (molar mass & 30.1 g/mol) occupies 1.2 x 10 -2 m3 at 46°C and 2.4 x 105 Pa. How many moles of ethane are present in the sample? What is the mass of the
The free surface of a liquid always has a tendency to contract and possess minimum surface area. If we want to enhance the surface area of the liquid, work has to be done. This wor
Regard as a capacitor which is charged to 12 volts and then connected across a resistor. Allow t1/2 be the time it takes for the voltage to drop down to 6 volts. Presume the experi
Describe your view about piezoelectric generator. Piezoelectric generator: A slab of piezoelectric crystal is acquired and using that parallel plate capacitor is made. After
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.
