Show the mathematical relation connecting n,u,v and R for refraction at a spherical surface concave towards a point object in a denser medium producing a virtual image.
Electric field lines In good metallic conductors: In good metallic conductors: (i) Static electric fields are not there (zero inside a conductor) (ii) Charges reside
A copper rod which is 1 centimetre in diameter carries a current of 5 amps. The current is distributed uniformly over the rod. The magnetic field half way among the axis o
Resistance: Resistance is the opposition to the motion of electrons. This arises as a result of collision of moving electrons. The unit of resistance is "ohm" represented by
Why magnetic poles are reversed at a given position on a deflection magnetometer to take readings? The magnetic moment of the magnet is 30 A-m 2 . Its length 10cm. What is its
A microphone is attached to a spring that is suspended from the ceiling. Directly below on the floor is a stationary 440 Hzsource of sound. The microphone vibrates up and down in s
Electrical work: Electrical work is done if a quantity of charge (coulombs) is moved between two points which are at different electrical potentials. The SI unit of work
The record for the highest speed achieved in laboratory for a uniformly rotating object was 2.01*10^3 m/s for a0.15-m long carbon rod. What was the period of rotation of the rod?
Calculate the current needed in a 240 mm length of conductor of a d.c. motor when the conductor is situated at right-angles to the magnetic field of flux density 1.25T, if a force
The waves which do not needs medium for their propagation are known as non- mechanical or electromagnetic waves. Examples : Light, heat (Infrared), radio waves, gamma- rays, X-r
