A collection of one mark and two marks questions from ELECTROSTATICS. Practise these for scoring a better and winning the edge over your coscholars!
Time: 45 min Max. Marks: 25 How does the force between two point charges change, if the dielectric constant of the medium in which they are kept, increases?  Name the experiment which established the quantum nature of electric charge.  Ordinary rubber is an insulator, but the special tyres of aircrafts are made slightly conducting. Why…… Continue reading Electrostatics : A Practice Test Paper – 1
PHYSICS TEST (CLASS XI) Kinematics A particle is projected at 60º to the horizontal with a kinetic energy K. What is the kinetic energy at the highest point Which of the following statements is false for a particle moving in a circle with a constant angular speed? (a) the velocity vector is tangent to the…… Continue reading Numericals from Kinematics
Each question carries one mark What is a magnetic dipole? What is the difference between electric field lines and magnetic field lines? Write an expression for the magnetic field at a point on the axis of a circular group carrying current and hence write equation for the magnetic dipole moment of the loop? What is…… Continue reading A Random Test from Magnetism
1. What orientation of an electric dipole in a uniform electric field corresponds to its stable equilibrium? 2. What is the area of the plates of a parallel plate capacitor of capacitance 2F and with separation between plates 0.5 cm? 3. What is the work done in carrying a point charge 10 nC between…… Continue reading ELECTROSTATICS TEST PAPER FOR CLASS XII
