What changes will be observed in an electric cell if the electrodes used in it are brought very close to each other and if their size are increased?

What will happen if the electrodes of a cell are placed closer to each other and if their size is made larger?

What change will be observed in the interference pattern produced in Young' s double slit experiment, if blue colour of the same intensity is used instead of yellow colour?

What change will you observe if the whole arrangement used in Young's double slit experiment is immersed in water?

Define surface density of electric charge. Two large conducting spheres carrying charges Q_(1) and Q_(2) are brought close to each other. Is the magnitude of the electrostatic force between them exactly given by (Q_(1)Q_(2))/(4 pi epsilon_(0)r^(2)) where r is the distance betwen their centres?

12 cells each having the same emf are connected in series and are kept in a closed box. Some of the cells are wrongly connected. This battery is connected in series with an ammeter and two similar cells . The current is 3A when the two cells aid the battery and is 2A when the cells and the battery oppose each other. How many cells in the battery are wrongly connected?

Two large conducting sphere carrying charges Q_(1) and Q_(2) are brought close to each other. Is the magnitude of the electrostatic force between them exactly given by Q_(1) Q_(2) //4pi in_(0) r^(2) , where r is the distance between their centres ?

Determine what effect auxin has on the cell wall as the cell size increases.

you have several identical electric cells. IF the internal resistance of the cells be (i) very much greater (ii) very much smaller than external resistance, then how should the cells be connected with that resistance to increase the current through it?

n electric cells of emf e and internal resistance r each are connected in series.What is the emf of this combination.
