Hint Analysis Figure of forces acting on the balls Solution Given values and numerical insertion: Thus, we can say that repulsion is the surest test of electrification. Note . While a negatively charged rod is held near, but not touching sphere A, someone moves ball B away from A. . Note that Newton's third law (every force exerted creates an equal and opposite force) applies as usualthe force on is equal in magnitude and opposite in direction to the force it exerts on . (i) attract each other, (ii) repel each other, or (iii) exert no force on each other? Applying Newtons second law of motion for any one of the sphere, we get. On being charged the spheres, which were originally in contact, take up positions with their centers 5 cm apart. The figure shows two tiny 5.0-g spheres suspended from very light 1.0-m-long threads.
