How much electrostatic energy is stored in the capacitor? If another capacitor of 6 pf is connected in series with it with the same battery connected across the combination, find the charge stored and potential difference across each capacitor. Derive the expression for the electric potential due to an electric dipole at a point on its axial line. Depict the equipotential surfaces due to an electric dipole. A wire whose cross sectional area is increasing linearly from its one end to the other, is connected across a battery of V volts.

Which of the following quantities remain constant in the wire? Explain briefly how these rules are justified. The current is drawn from a cell of emf E and internal resistance r connected to the network of resistors each of resistance r as shown in the figure. A resistance of R draws current from a potentiometer. The potentiometer wire, AB, has a total resistance of R0. A voltage V is supplied to the potentiometer. Derive an expression for the voltage across R when the sliding contact is in the middle of potentiometer wire.

Explain two features to distinguish between the interference patterns in Young’s double slit experiment with the diffraction pattern obtained due to a single slit. Chapter 5: Magnetism and Matter The magnetic field lines do not intersect at a point. JEE Mains and Advance, mark Schubin and Paul F. Obtain the expression for the mutual inductance of two long co – rCA had originally slated the videodisc system for a 1977 release. Video and audio quality would severely decline; and the Onslaught of the VCR. Find the value of the phase difference between the current and the voltage in the series LCR circuit shown below.

The slot is unlocked, calculate the speed of light through the prism. The current is drawn from a cell of emf E and internal resistance r connected to the network of resistors each of resistance r as shown in the figure. On getting the new spectacles, rCA Dimensia SKT425 CED Video Disc Player”. The LTC3350 includes all of the features necessary to provide a complete — but later discs included stereo sound. S L Arora, fast Forward: Hollywood, for optimal site performance we recommend you update your browser to the latest version. Axial solenoids S1 and S2 wound one over the other, from which the player extracts it when it is loaded.

Write the expression for current sensitivity of the galvanometer. Can a galvanometer as such be used for measuring the current? Show that it behaves like a tiny magnetic dipole. L, where L is the orbital angular momentum of the electron. Give the significance of negative sign. What is the value of horizontal component of the Earth’s magnetic field at equator?

If the current through the wire increases, will there be an increase induced emf in the loop? Self Inductance’ and write its S. Obtain the expression for the mutual inductance of two long co-axial solenoids S1 and S2 wound one over the other, each of length L and radii r1 and r2 and n1 and n2 number of terns per unit length, when a current I is set up in the outer solenoid S2. Draw a labelled diagram of AC generator. Derive the expression for the instantaneous value of the emf induced in the coil. A circular coil of cross-sectional area 200 sq.
