Question

When are two vectors equal?

विकल्प

• Their magnitudes are equal.

• Their \[\hat{i}\] components are equal only.

• Their corresponding components are equal.

• One is a scalar multiple of the other.

Answer 1

Two vectors are equal if their corresponding components are equal. Equality requires agreement of all the \[\hat{i}\], \[\hat{j}\], and \[\hat{k}\] components.
