Write T against true and F against false in the following statements:
(a) Like charges attract each other (T/F)
(b) A charged glass rod attract a charged plastic straw (T/F)
(c) Lightning conductor cannot protect a building from lightning (T/F)
(d) Earthquakes can be predicted in advance (T/F)
Answer
(a) False
Like charges repel each other.
(b) True
A charged glass rod has positive charge and a charged plastic straw has a negative charge.
Since opposite charges attract each other, they attract each other.
(c) False
During lightning, the lightning conductor conducts the lightning directly to the earth and hence saves the building from lightning.
(d) False
Earthquakes can not be predicted in advance.
