Two point charges, one q and the other – q, form a dipole separated by a distance d. A third charge Q is placed midway between these two charges. If the distance between q and – q is then doubled with the Q staying midway between the other two, what happens to the force on Q?

it will reduce by 4

Explanation:

From Coulomb's law,

Force is inversely proportional to distance of separation between the centre of the two charges.

when d is doubled, the force between q and -q will reduce by a factor of 4 same also applies to the force on Q and any of q or -q

small = small current large mag large current

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
