Write $T$ against true and $F$ against false in the following statements:
$\left( A \right)$Like charges attract each other. $\left( {T/F} \right)$
$\left( B \right)$A charged glass rod attracts a charged plastic straw. $\left( {T/F} \right)$
$\left( C \right)$A lightning conductor cannot protect a building from lightning. $\left( {T/F} \right)$
$\left( D \right)$Earthquakes can be predicted in advance. $\left( {T/F} \right)$

Hints: So for answering the above question we should have to know the properties of electric charges and also there should be a good understanding of charges. Below true false will be answered with the appropriate reasons.
Answer
One by one explanation of the above question has been given:
$\left( A \right)$So the statement given is false and as charges can never attract each other they will always repel one another.
$\left( B \right)$So the given statement said in this question is true. As when there are both objects oppositely charged then they will attract each other. In the same way here a charged glass rod will attract a charged plastic straw since both of them are oppositely charged.
$\left( C \right)$ So the given statement said in this question is false. When lightning happens, the atmospheric charges are transferred to the earth directly by a lightning conductor. Thus the building is shielded from lighting. A lightning conductor always helps in protecting the high building and tower from the lightning by conducting all the charges to the ground or we can say earth directly.
$\left( D \right)$So the given statement said in this question is false. As the earthquakes cannot be predicted to date as there is no such device or equipment made to detect the earthquakes in advance. If such a thing came then the place which is more prone to this would become safer for staying there. Even though the earthquake causes are noted, there are no instruments that are fabricated to sight them before. Thus earthquakes cannot be expected in advance.
Notes: Various ways in which to guard ourselves against lighting area unit (i) continuously stay in a much-closed place and if you're in a very automotive keep there till the lighting is over and keep the windows closed. (ii) Never touch any electrical wires, telephone cables, metal pipes. (iii) Never tub in running water, this might cause electrical shock.
