In a hot star, a multiply ionized atom with a single remaining electron produces a series of spectral lines as described by the bohr model. the series corresponds to electronic transitions that terminate in the same final state. the longest and shortest wavelengths of the series are 63.3 nm and 22.8 nm, respectively. (a) what is the ion? (b) find the wavelengths of the next three spectral lines nearest to the line of longest wavelength.

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.
