Which statement best describes how the monopole would be used to describe magnetic field lines?

The field lines around a magnet point from the south pole to the north pole to show the direction opposite to the magnetic force on the monopole.
The field lines around a magnet point from the south pole to the north pole to show the direction of the magnetic force on the monopole.
The field lines around a magnet point from the north pole to the south pole to show the direction opposite to the magnetic force on the monopole.

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.
