Statement I: If a particle projected horizontally just above, the surface of the earth with a speed greater than escape speed, then it will escape from gravitational influence of the earth. Assume that particle has a clear path. Statement II: Escape velocity is independent of its direction.

A projectile of mass mis fired with an initial velocity v_(0) at an angle 0 to the horizontal. At its highest point, it explodes into two fragments of equal mass. One of the fragments falls vertically with zero initial speed. Since the only external force acting on the system is gravitational, the motion of centre of mass of the_ system (the fragments) follows the same parabolic path as the projectile would have followed if there had been no explosion. Force of explosion is internal, it cannot change the trajectory of the system.

Statement I : The fringe obtained at the centre of the screen in known as zeroth order fringe or central fringe. Statement II: Path difference between the waves from S_1 and S_2 reaching the centre is zero.

An object is project with a speed 10ms^(-1) at an angle of 30^@ with the horizontal. It breaks into n equal fragments during its motion . One fragment strikes the ground at a distance of sqrt(3)m from the point of projection. The centre of mass of the remaining fragments strikes the ground at a distance of 7sqrt(3)m from the point of projection . If all fragments strike the ground at the same time , Find the value of n.

A shell is fired from the ground at an angle theta with horizontal with a velocity 'v'. At its highest point it breaks into two equal fragments. if one fragment comes back through its initial line of motion with same speed then the speed of the second fragment will be .

An object of mass 5 kg is projected with a velocity of 20 m/s at angle of 60° to the horizontal. At the highest point of its path, the projectile explodes and breaks up into two fragments of masses 1 kg and 4 kg. The fragments separate horizontally after the explosion. The explosion releases internal energy such that the kinetic energy of the system at the highest point is doubled. If the separation between the two fragments when they reach the ground is x, then find the value of x/(5sqrt(3)) .

Statement -1 : Two projectiles are launched from the top of a cliff with same initial speed with different angles of projection. They reach the ground with the same speed. Statement -2 : The work done by gravity is same in both the case

Statement-1 : A thin uniform rod is undergoing fixed axis rotation about one its end with variable angular accleration. Then acceleration vector of any two moving point on the can not be parallel at an instant of time. Statement-2: for a rod undergoing fixed axis rotation, the velocity of any two moving points on the rod at different distances from centre of rotation are different.
