Figure 6.26 shows a flywheel of mass 12 kg and radius 50 cm with a rope wrapped around it. On the end of the rope is a
2.0 kg load. Initially it is at rest.
a) Calculate the torque on the flywheel. Assume g to be
9.8 m/s.
b) Work out what its angular momentum will be after 2.5 s.
Angular momentum is a vector and so will have a direction. You
can use the right-hand rule to show its direction.​

the answer is b, have negligible mass

more than, less

less than, more

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.
