Question

Assertion(A): A vector is not changed if it is slid parallel to itself
Reason(R): Two parallel vectors of same magnitude are said to be equal vectors

• A. Both A and R are true and R is correct explanation of A
• B. Both A and R are true, but R is not correct explanation of A
• C. A is true, but R is false
• D. A is false, but R is true

Answer 1

Answer: (B)

Both A and R are true, but R is not correct explanation of A

Vector is defined by its direction and its magnitude but not by its position in space i.e. if a vector is displaced parallel to itself (without changing its magnitude and its direction) then it does not change , it remains equal.

The reason given is a condition for parallel vectors of same magnitude and is not the correct explanation for the assertion.
