Solution:
#### 1. The rods are charged by ___________. This is done by ___________ the rods with a woollen cloth.
-
Answer:
- The rods are charged by
friction.
- This is done by
rubbing the rods with a woollen cloth.
#### 2. Inside the nucleus of an atom there are p__________ and n__________.
-
Answer:
- Inside the nucleus of an atom there are
protons and
neutrons.
#### 3. Around the nucleus there are ____________ (in orbits).
-
Answer:
- Around the nucleus there are
electrons (in orbits).
#### 4. Charging is due to the transfer of ____________ from one material to another.
-
Answer:
- Charging is due to the transfer of
electrons from one material to another.
#### 5. When an object gains electrons it becomes ____________ charged because electrons have a ____________ charge.
-
Answer:
- When an object gains electrons it becomes
negatively charged because electrons have a
negative charge.
#### 6. An object becomes positively charged when the object ____________ electrons (electrons are transferred to the cloth or another material).
-
Answer:
- An object becomes positively charged when the object
loses electrons (electrons are transferred to the cloth or another material).
#### Attraction and Repulsion Forces Due to Static Electricity
#### 7. Like (same) charges ____________.
-
Answer:
- Like (same) charges
repel.
#### 8. Unlike (different) charges ____________.
-
Answer:
- Unlike (different) charges
attract.
#### 9. If I place a charged polythene rod to another freely suspended charged polythene rod, they will ____________ each other because they have the ____________ charge.
-
Answer:
- If I place a charged polythene rod to another freely suspended charged polythene rod, they will
repel each other because they have the
same charge.
