Part 2

Two identical charges +Q are kept fixed some distance apart. A small particles P with charge q is placed midway between them . If P is given a small displacement Δ ,it will undergo simple harmonic motion if (i) q is positive and Δ is along the line joining the charges (ii) q is positive [...]

Two small balls having equal positive charges Q( coulomb) on each are suspended by two insulating strings of equal length L(metre) from a hook fixed to a stand. The whole set up is taken in a satellite into space where there is no gravity (state of weightlessness). Then angle between the two strings is. Two [...]

Two points charges Q1 and Q2 placed at separation d in vacuum and force acting between them is F. Now a dielectric slab of thickness d/2 and dielectric constant K=4 is placed between them. The new force between the charges will be Two free charges q and 4q are placed at a distance d apart. [...]

In the following diagrams a particle with small charge −q is free to move up or down , but not sideways near a larger fixed charge Q. The small charge is in equilibrium because in the positions shown ,the electrical upward force is equal to the weight of the particle .Which statement is true? but [...]

Two point charges q1=+2C and q2=−1C are separated by a distance d. The position on the line joining the two charges where a third charge q=+1C will be in equilibrium is at a distance Two point charges q1=+2C and q2=−1C are separated by a distance d. The position on the line joining the two charges [...]

Two free charges q and 4q are placed at a distance d apart. A third charge Q is placed between them at a distance x from charges q such that the system is in equilibrium. Then Two free charges q and 4q are placed at a distance d apart. A third charge Q is placed [...]

A capacitor of capacity C1 is charged upto potential V volt and then connected in parallel to an uncharged capacitor of capacity C2 . The final potential difference across each capacitor will be : A capacitor of capacity C1 is charged upto potential V volt and then connected in parallel to an uncharged capacitor of [...]

The capacities of two parallel plate capacitors are C1 and C2 and their respective potential are V1 and V2. If they are connected by a thin wire, then The capacities of two parallel plate capacitors are C1 and C2 and their respective potential are V1 and V2. If they are connected by a thin wire [...]

A potentiometer circuit has been set up for finding the internal resistance of a given cell. The main battery, used across the potentiometer wire, has an emf of 2.0V and a negligible internal resistance. The potentiometer wire itself is 4m long. When the resistance R, connected across the given cell, has values of (i) infinity [...]
