When a particle of mass m is at (x comma 0 ), it is attracted toward the origin with a force whose magnitude is startfraction y over x squared endfraction . if the particle starts from rest at x equals b and is acted upon by no other forces, find the work done on it by the time it reaches x equals a, 0 less than a less than b.
