CIE Physics Paper-1: Specimen Questions 97 - 98 of 109
Question number: 97
The diagram shows a torch containing two batteries, a switch and a lamp.
What is the circuit diagram for the torch?
According to figure of the torch both cells are in series with battery and bulb. So only figure of choice A gives this type of proper arrangement of the electric component. So choice A is correct.
Question number: 98
A polythene rod repels an inflated balloon hanging from a nylon thread. What charges must the rod and the balloon carry?
The balloon is charged but the rod is not.
The rod and the balloon carry like charges.
The rod is charged but the balloon is not.
The rod and the balloon carry opposite charges.
The like charges always repel and the opposite charges always attract to each other.
Here a polythene rod repels an inflated balloon hanging from a nylon thread. Therefore rod and balloon carry like charges.
