an object of mass 30kg is falling in air and experiences a force due to air resistance 50N. (a). determine the net force acting on the object and (b). calculate the acceleration of the object

the body's situation won't change the forces are equal opposit and on the same body

scientific laws are the result of testing theories and proving them to be facts.

it doesn't. it was imagined up in the middle ages.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
