Wave and particle behaviours of electrons De Broglie (matter) waves. The Compton experiment (conclusions). Newton’s Laws. Inertial and Non-inertial frames of reference. Relativistic effects.
D-t , V-t, a-t graphs. Electrostatic fields. (parallel plates), Motion of particle in uniform and non-uniform electric and magnetic fields. Electric Potential.. Elastic and Inelastic collisions. Conservation of momentum. Vectors (River) Crossing problems Circular motion: direction of vel and accel. Static and kinetic friction.
There will be 40 multiple choice questions. 20 marks Short answer questions.
