The mass of M is greater than N. Which of the following shows their equilibrium positions? 2 / 5 2) A positively-charged oil drop is suspended at rest at position P between two charged plates as shown. What will happen to the same positively-charged oil drop if it is at position Q? The oil drop will remain at rest. The oil drop will move at constant speed towards the negative plate. The oil drop will move at constant speed towards the positive plate. The oil drop will accelerate towards the negative plate. 3 / 5 3) The build-up of static charge on the body of a petrol tanker, that may trigger an explosion, can be prevented by using an insulator to make the body of the truck. coating a conducting layer on the body of the truck. fixing a metal grid at the bottom of the truck. suspending a conducting strip from the truck onto the ground. 4 / 5 4) An electrostatically charged object will pick up small pieces of paper. A student rubbed the following items together and tried to pick up small pieces of paper. Which of the following will not pick up the pieces of paper? A plastic comb pulled through dry hair. A metal rod rubbed with a duster. A rubber balloon rubbed with a nylon shirt. A polythene rod rubbed with a woollen cloth. 5 / 5 5) The diagram shows three identical positive charges P, Q and R, which are placed between two charged metal plates. Which statement about the force exerted on each charge P, Q and R by the electric field between the plates is correct? P and R experience the strongest force while Q experiences the weakest. The forces experienced by each of the three charges are the same. P and R experience the weakest force while Q experiences the strongest. P experiences the weakest force while R experiences the strongest. Your score is Restart quiz
