True or False: By rubbing, some objects such as a glass rod or an ebonite rod with silk or fur, a/an repulsive force can be produced. Explain your answer.
. In a common physics demonstration, a rubber rod is first rubbed
vigorously on silk or fur. It is then brought close to a small Styrofoam™ ball, which it attracts. If you then touch the ball with the rod,
it suddenly repels the ball. Why does it first attract the ball, and why
does it then repel the same ball?
Ordinary rubber is an insulator. But special rubber tyres of aircraft are made slightly conducting. Why is this necessary?

The pattern on the paper is controlled by an electrostatic valve that determines at each nozzle position whether ink is squirted onto the paper or not. Figure 9 Do 163 Ē T 1 of 1 The ink drops have a mass m = 1.00×10-11 kg each and leave the nozzle and travel horizontally toward the paper at velocity = 24.0 m/s. The drops pass through a charging unit that gives each drop a positive charge q by causing it to lose some electrons. The drops then pass between parallel deflecting plates of length Do = 1.50 cm, where there is a uniform vertical electric field with magnitude E= 8.15x104 N/C. (Figure 1) Part A If a drop is to be deflected a distance d = 0.250 mm by the time it reaches the end of the deflection plate, what magnitude of charge q must be given to the drop?
