calculate the work done to stretch an elastic string by 50cm, if a force of 12.5N produces an extension from it.​

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

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

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
