Leave out the the phrase "would make the X-sphere positively charged". This incredible eBook offers every Shakespearean play, poem, apocryphal work and much, much more! C. remain in the negatively charged, A stream of positively-charged particles is moving to the left in a magnetic field. If the spheres maintain a constant distance x, while they are kept apart by the repulsive Coulomb force, then there is no charge loss. Then touch both pith balls with the rod. Ah I see, Thanks. If the spheres are first brought into contact and then separated to the original distance, then the ratio of the new force to the previous force is Two equal small spheres each weighing 1g , hang by two equal silk threads from the same point. Some two hundred and fifty feet high, rising straight from the sea ten miles from land, with the whole mountainous group to the south and east.
