A 50kg mass initially at rest explodes into two fragments. The 30kg fragment moves west at 40m/s. What is the velocity of the 20kg fragment?

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

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
