Total Marks: 20

1. A positive eletrice charge:
Attracts positive charge Repels other positve charge Attracts a neutral charge Repels a neutral charge
2. An object gains exess nagetive charge after being rubbed against another object which is:
Negatively charged Positively charged Neutral Either a, b or c
3. Two uncharged object A and B are rubbed against each other. When object B is placed near a negatively charged object C, the two objects repel each other. Which of these statements is true about object A?
Remains uncharged Becomes negatively charged Becomes positively charged Unpredictable
4. When you rub a plastic rod against your hair several times and put it near some bits of paper, the pieces of papers are attracted towards it.What does this observation indicate?
The rod acquires a positive charge The rod and the paper have the same charged The rod acquires a negative charge The rod and the paper are oppositely charged
5. According to Coulomb’s law, what happens to the attraction of two oppositely charged objects as their distance of separation increases?
Increases Decreases Remains unchanged Cannot be determined
6. The coulomb’s law is vaild for the charges which are
Moving and point charges Moving and non-point charges Stationary and point charges Stationary and large size charges
7. A positive and a negative charges are initially 4 cm apart. When they are moved closer together so that they are now only 1cm apart, the force between them is
4 times smaller than before 4 times larger than before 8 times larger than before 16 times larger than before
