The electrostatics force of repulsion between two positively charged ions carrying equal charge is `3.7xx10^(-9)N` when these are separated by a distance of `5Å`. How many electrons are missing from each ion?

The electrostatic force of repulsion between two positively charged ions carrying equal charge is 3.7xx10^(-9)N , when they are separated by a distance of 5Å . How much electrons are missing from each ion?

The magnitude of the electrostatic force between two identical ions that separated by a distance of 10.0 xx 10^(-10)m is 9.25 xx 10^(-10)N . (a) What is the charge of each ion ? (b) How many electrons are "missing" from each ion (thus giving the ion its charge imbalance) ? (c ) What is the force magnitude if the separation is halved ?

Two infinitesimally small bodies are charged by rubbing against each other are found to attract each other with a force of 3.7xx10^(-13) N when separated by a distance of 5xx10^(-8) m. How many electrons were transferred from one body to the other after rubbing ?

The force of repulsion between two point charges is F, when they are d distance apart. If the point charges are replaced by conducted sphereas each of radius r and the charges remain same. The separation between the centre of sphere isd, then force of repulsion between them is

When ferric ion is formed from ferrous ion, the positive charge is increased by two units.

The force of repulsion between two point charges is F, when these are at a distance of 1 m . Now the point charges are replaced by spheres of radii 25 cm having the charge same as that of point charges. The distance between their centres is 1 m , then compare the force of repulsion in two cases.

The force of repulsion between two point charges is F, when these are at distance 0.5m apart. Now the point charges are replaced by spheres of radii 5 cm each having the same charge as that of the respective point charge. The distance between their centres is again kept 0.5 m. Then the force of repulsion will

(a) Two insulated charged copper spheres A and B have their centers speparated by a distance of 50 cm. What is the mutal force of electrostatic repulsion if the charge on each is 6.5xx10^(-7) C ? The radill of A and B are negalible compared to the distance of separation. (b) What is the force of repulsion if each sphere is charged double the above amount, and the distance between them is halved ?
