Two charges, each of magnitude one coulomb, are placed at a distance of 1 meter from each other. If they...

Two charges of values 2 muC and -50 muC are placed at a distance of 6 cm from each other. The distance of the point (in cm) from the bigger charge where the electric intensity will be zero is :

Two copper pieces, each of mass 0.0635 kg are placed at a distance of 0.1 m from each other One electron from each atom of piece 1 is transferred to piece 2 of copper. Net charges on piece 1 and piece 2 after transfer of electrons respectively will be

Two point charges with charge magnitudes 2 nC and 3 nC are placed at a separation of 1 cm from each other and then released. The mass of each point charge is 1 mu g. Find the magnitude of acceleration of particles at the instant they are released.

Two point charges, each of mass m and charge q are released when they are at a distance from each other. What is the speed of each charged particle when they are at a distance 2r ?

Two charges of equal magnitudes and at a distance r exert a force F on each other. If the charges are halved and distance between them is doubled, then the new force acting on each charge is

Two equal charges of magnitude Q each are placed at a distance d apart. Their electrostatic energy is E. A third charge -Q//2 is brought midway between these two charges. The electrostatic energy of the system is now

An ionfinite number of charges each q are placed in the x-axis at distances of 1,2,4,8 meter from the origin. If the charges are alternately positive and negative find the intensity of electric field at origin.

Two points charges q_1 and q_2 are placed at a distance of 50 m from each each other in air, and interact with a certain force. The same charges are now put in oil whose relative permittivity is 5. If the interacting force between them is still the same, their separation now is
