Question

2) What happens when a glass rod is rubbed against silk thread ?

3) What are the laws of Magnetic poles ?

4) What is static electricity ?​

Answer 1

• When a glass rod is rubbed with silk, glass rod loses electrons and silk gains electrons. Glass rod becomes positively charged and silk becomes negatively charged. For example, suppose a glass rod has 10 protons and 10 electrons and silk has 7 electrons and 7 protons.
• Magnetic pole, region at each end of
• amagnet where the external magnetic
• fieldis strongest. ... The south-seeking pole,
• or any pole similar to it, is called a
• southmagnetic pole. Unlike poles of different
• magnets attract each other; like poles repel
• each other.
• Static Electricity
• is electricity that does not
• moveong a path.

A. It collects on a surface

B. It is caused by friction or rubbing.

C. Friction either adds or removes

electrons from surface atoms.
