When studying atoms, scientists can ignore the 'BLANK' force between charged particles that make up the atoms because it is many millions of times smaller than other forces in the atom.

it takes about 30 days for it to break down

d.7.5cm is your answer

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.

the right answer is 0.3 meters per second
