How much work would be required to move an electron from 0.0529 × 10-9 m from a proton to four times that distance?

Question

experimentx · Answer

calculate the difference in potential energy.

anonymous · Answer

Work done =  Force*displacement

Calculate force between electron and proton when distance between them is 0.0529 × 10-9 m and multiply by the displacement :)

@shivam_bhalla your answer doesn't seem to be correct.. The magnitude of force is not going to remain as the electron keeps moving.. the magnitude of force on electron will go on decreasing with increasing distance.. So you can't just use work=force*displacement..

You can use method of integration. or else as mentioned by @experimentX find the difference in potential energy..
