Which of the following statements are true concerning the creation of magnetic fields? check all that apply. check all that apply. a permanent magnet creates a magnetic field at all points in the surrounding region. a single stationary electric charge creates a magnetic field at all points in the surrounding region. an electric current in a conductor creates a magnetic fiel

as technology advances, new experiments often expose problems in accepted theories. c

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
