    In Rutherford experiment ,very few of the alpha particles scatter through large angles. Why ?

    In Rutherford's experiment , which particle is reponsible for the low angle scattering of alpha -particles ?

    Statement I : A system of three positive charges, each having a charge q and placed at equal distance from each other along a straight line cannot be in equilibrium. Statement II : The charge in the middle experiences zero net force, but the force acting on the charges at the extreme ends is not zero.

    Statement I : Acceleration of a moving particle can change its direction without any change in the direction of velocity. Statement II : If the direction two particles moving with constant velocities always remains vector also changes.

    Statement : I The velocity of ejection of a charged particle, being accelerated in a cyclotron remains constant irrespective of the applied magnetic field. Statement : II In a cyclotron the charged particle is accelerated only due to the applied electric field because magnetic force is a no-work force.
