Asquare loop of wire with side length 10 cm is moving to the right with constant speed of 16 m/s. the loop has total resistance of 0.8 ohms. it begins in a region with no magnetic field, then enters a region of magnetic field (wider than 10 cm) with a strength of 0.5 t pointing out of the page. finally it leaves the field. 1. when totally in the field, what is the magnitude of the magnetic flux through the loop? 2. as the loop enters the field, what is the magnitude of the induced emf around the loop?

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.
