Consider a thin slice of the first rod, of thickness dx1, that is located a distance x1 from the origin and a thin slice of the second rod, of thickness dx2, that is located a distance x2 from the origin. Enter an expression for the magnitude of the force dF12 that the thin slice of rod 1 exerts on the thin slice of rod 2, in terms of L1, L2, Q1, Q2, x1, x2, and the Coulomb constant k.

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.
