Static electricity

1. +ve/ -ve charges

1.1. in a positive charge, the electric field lines point outwards

1.2. In a negative charge the electric field lines point inward.

2. various materials that produce charge when rubbed.

2.1. Amber rubbed with fur.produces positive charge.

2.2. rubber rubbed wit fur produces positive charge.

2.3. glass rubbed with silk cloth produces negative charge.

2.4. polythene rubbed with wool produces negative charge,

4.3. electrocution

5. field lines

5.1. the line starts from the positive charge and ends on the negative charge.

5.2. Any line drawn from the positive charge and ending on a negative charge is proportional to the magnitude of the charge.

5.3. Two field lines cannot cross each other.
