A gold rod of length `l` is accelerated in the horizontal direction with an accleration `a_(0)`. The rod is held between two perfactly insulating clamps. Calculate the electric field set up in the rod. Take the mass of electron as `m`.

A uniform rod of length L and mass m is free to rotate about a frictionless pivot at one end as shown in figure. The rod is held at rest in the horizontal position and a coin of mass m is placed at the free end. Now the rod is released The reaction on the coin immediately after the rod starts falling is

One fourth length of a uniform rod of length 2l and mass m is place don a horizontal table and the rod is held horizontal. The rod is released from rest. Find the normal reaction on the rod as soon as the rod is released.

A uniform rod of mass m and length 2L on a smooth horizontal surface. A particle of mass m is connected to a string of length L whose other end is connected to the end ‘A’ of the rod. Initially the string is held taut perpendicular to the rod and the particle is given a velocity v_(0) parallel to the initial position of the rod. (a) Calculate the acceleration of the centre of the rod immediately after the particle is projected. (b) The particle strikes the centre of the rod and sticks to it. Calculate the angular speed of the rod after this.
