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.
A particle moving in a straight line with constant accelaration is having initial velocity of 10 m/s. After some time, the velocity becomes 30 m/s. Find the velocity of particle at
A box is initially at rest on a horizontal, frictionless table. If a force of 10 Newtons acts on the box for 3 seconds, what is the momentum of the box at the end of the 3 second i

Necessity Of A Starter For D.C Motors When motor is at rest, then N=0 and due to Eb is directly proportional to N, so At begin E b = zero Thus armature current at t
For the system shown below the gain, G, of block A is variable and can be set as low as 100 and as high as 500. The only problem with block A is that its gain fluctuates with high
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.
