Statement I : The sum of two vectors can be zero.
Statement II : The vector cancel each other, when they are equal and opposite.

Moderate

A

If both statement I and statement II are true and statement II is the correct explanation of statement I.
B

If both statement I and statement II are true but statement II is not the correct explanation of statement I.
C

If statement I is true but statement II is false.
D

If both statement I and statement II are false.

Solution

Let $\vec{P} and \vec{Q}$ are two vectors in opposite direction, then their sum $\vec{P} + (- \vec{Q}) = \vec{P} - \vec{Q} . If \vec{P} = \vec{Q}$ then sum equal to zero.
