B се 450 In Fig. 2, the partioles A and B, of mass 8 kg and 6 kg respectively, are connected by a light inextensible string which passes over a smooth pulley fixed at C. A lies on a rough horizontal plane and B lies on a smooth plane inclined at 45° to the horizontal. The coefficient of friction between A and the plane is u. The system is in limiting equilibrium. Find the value of H Given that Bis replaced with another particle of mass 8 kg, find (a) the acceleration of the system, (b) the tension in the string. Fig. 2 (Take g asi0 ms-*) ce

Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.
