Which of the following statements is correct? Both spheres are at the same electric potential after equilibrium is established. A momentary conventional current will flow from the small sphere. The large sphere will acquire a net negative charge. The charges on the small sphere will be neutralised. 2 / 5 2) When a polythene rod is charged negatively by friction, it loses electrons. it loses electrons. it gains electrons. it gains protons. 3 / 5 3) Two identical light conducting balls with charges +5 C and –3 C are suspended freely and brought towards each other as shown. Which of the following shows the positions of the two balls after they touch? 4 / 5 4) A negatively charged oil droplet is allowed to fall between two charged metal plates as shown in the following figure. Which of the following actions will cause the oil droplet to fall faster? Use a lighter oil droplet with the same amount of negative charge on it. Reverse the polarity of the plates. Add more negative charge to the oil droplet. Increase the voltage between the plates. 5 / 5 5) A negatively charged metal sphere is shown below. If this sphere is earthed, what will be the resulting distribution of charge on it? Your score is Restart quiz
