Two equal charges with magnitude q and q experience a force of 12.3442 when held at a distance r. what is the force between two charges of magnitude 2*q and 2*q when held at a distance r/2.?

197.5072.

Explanation:

According to the Coulomb's law, the magnitude of the electrostatic force of interaction between two charges and which are separated by the distance is given by

where, k is the Coulomb's constant.

For the case, when,

Then, using Coulomb's law,

For the case, when,

Then, using Coulomb's law, the new electric force between the charges is given by,

chemical properties of thing

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
