Question

When the force increase and the time also increases or when the force increase and the time decrease and when a force decrease and the time decrease why solve this question

Answer 1

depends on the nature of force. its wrong intuition that if a force is applied for longer period of time it will increase… for applying the force for longer time more energy will be required.if sufficient energy is not available, after some time that force will die away.therefore the force reduces with time. electromagnetic forces experienced in atomic scale are time-varying, to be specific it is sinusoidal (sine/cosine).the force experienced is a sine curve. it increases then decreases with time periodically. if a constant force is applied. it wont if a time varying force is applied.it will increase/decrease according to how it varies.
