Trace the path of a ray emitted from the tip of the object through the focal point of the mirror and then the reflected ray that results. start by extending the existing ray emitted from the tip of the object. then create the reflected ray. draw the vector for the reflected ray starting from the point where the incident focal ray hits the mirror. the location and orientation of the vector will be graded. the length of the vector will not be graded.

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.

i believe the answer is electric potential.
