Q.No.2.6: - Can the magnitude of a vector
have a negative value?
Ans: - No, the magnitude of a
vector cannot be a negative value it always has a positive value.
The magnitude of a vector is a scalar. As we know that a
vector in 2-D have x and y component generally but its has a square root which
have ± value means the vector may have a negative or a positive value but
negative magnitude have no sense so we always take the positive value.
(Conceptual example: - For example height is a scalar quantity
if we build a house then its height is always in upward direction means +
direction if we say that we build a house in downward direction then what does
it mean it seems very funny it has no proper sense.)

ReplyDeleteif we say that the value of magnitude is zero so where we can also say that negative magnitude
ReplyDeleteI guess only positive in real sense! Because the magnitude of a vector tracing cannot be negative.. Thank you..
