For the following, put T in the box if the statement is true, Fif it is false. Try to provide a very brief explanation of each answer.

a) Like chargs attract; unlike charges repel.

b) When polythene is rubbed with wool, positive charges move from the polythene to the wool.

c) Metal water pipes in the home can be used as an electrical earth.

d) The tip of a lightning conductor should have a sharp point.

e) It could be dangerous to fly a kite during thundery weather.

f) Blobs of solder on electrical equipment should be rounded rather than pointed.

g) A conductor allows protons to move through it easily.

thank you for your time!

There are three false. I will be happy to critique your thinking. As a note, there should be NO blobs of solder in electrical equipment, solder should be neat, with just enough to weld two materials.

what's this all about?

a. F . the reverse is true.

b. F. electron moves from wool to polythene.

c. T

d. T

e. T

f. T

g. F. it should be " allow electrons to move through it easily"

can you tell me about the true why??

thanks for your time

a) T - This statement is true based on the fundamental principle of electrostatics. Like charges (charges with the same sign) repel each other, while unlike charges (charges with opposite signs) attract each other.

b) F - When polythene is rubbed with wool, negative charges move from the wool to the polythene. This results in the polythene gaining a net negative charge and the wool gaining a net positive charge through the transfer of electrons.

c) T - Metal water pipes in a home can be used as an electrical earth. This means that they provide a pathway for electrical current to flow into the ground, thus protecting the home from electrical faults and providing a safe discharge route for excess electrical charges.

d) T - The tip of a lightning conductor should have a sharp point. This is because a sharp point creates a strong electric field, which helps to facilitate the dissipation of electrical charges and reduces the likelihood of lightning striking the protected structure.

e) T - It could be dangerous to fly a kite during thundery weather. The reason is that the kite string can act as a conductive path for lightning if it comes into contact with a charged cloud. This poses a significant risk of electric shock or being struck by lightning.

f) T - Blobs of solder on electrical equipment should be rounded rather than pointed. Rounded blobs distribute the stress and strain caused by thermal expansion and contraction more evenly, reducing the risk of mechanical failure and damage to the solder joints.

g) F - A conductor allows electrons (negatively charged particles) to move through it easily. Protons (positively charged particles) are relatively heavy and are not able to move through a conductor as freely as electrons.
