An electron is moving through a magnetic field. if the velocity of the electron is doubled, the magnetic force experienced by the electron will
a. stay the same
b. double
c. triple
d. quadruple

B. Double

Explanation:

As we know that the magnetic force on moving electron is given as

now we will have

here we know that the velocity of the electron is doubled and rest all components remains the same

so we will have

so the new force will be double that of initial force on the electron so correct answer will be

B. Double

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
