Which statement is true about a polarized object?
2 answers:
Answer: Option (3) is the correct answer.
Explanation:
When an object is polarized then it means that if a negatively charged object is brought near a neutral atom then a positive charge will develop on the neutral object near the area of contact.
Whereas a negative charge will develop on the opposite side neutral object which is not in contact with the negatively charged object.
Hence, in a polarized object there are equal number of both positive and negative charges.
Thus, we can conclude that the statement number of positive and negative charges can be the same, is true about a polarized object.

The correct option is (D) Gamma ( 
)
Explanation:
Now this question is a tricky one because all of these options are somehow involved in radioactive decay; however, in this case the SYMBOL is required NOT the elements. There are three symbols involved in radioactive decay, which are:
1. α for alpha decay
2. β for beta decay
3. γ for gamma decay
In the options only one symbol is present which is gamma. Hence option (D) Gamma ( ) is the correct answer.
