Which of the following is true? When objects become electrically charged, 1 point it is because *
A. Both protons and electrons may be moving on to or off of the object.
B. Only protons are moving on to or off of the object.
C. Only electrons are moving on to or off of the object.
D. Becoming electrically charged has nothing to do with the movement of protons or
electrons.
E. None of the above.

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.

not too sure thinking all accelerations are pointed down
