Q.

The following metal/s can be classified as poor conductor of electricity:

1. Mercury

2. Gold

3. Iron

4. Lead

Q. Differentiate between positive charge and negative charge.

Q. The flow of charged particles is called _________.

1. water current
2. electric current
3. electric circuit
4. circuit

Q. How do we know that a object is negatively charged or positively charged?

Q. Moving charges, which get transferred from one object to the other are negative charges only.

1. True
2. False

Q. Charges q, -q and q are placed at the points (-1, 1, 1), (1, -1, 1) and (1, 1, -1) respectively. What will be the x component of the electric field at the origin?

Q.

The diagram shown below explains that:

1. Like charges attract each other

2. Unlike charges repel each other

3. Like charges repel each other

4. Charges do not react with each other

Q.

When no charge is supplied to or removed from a neutral body, then the amount of……..

1. positive charge = negative charge in it

2. positive charge > negative charge in it

3. positive charge < negative charge in it

4. no charge is present in the body initially

Q. how do we exactly know that only negative charges flow as we can't see them ? so how do we know that the charges which are flowing are negative can't they be positive?

Q. What are the three properties of charges? Please answer me ASAP.
