Can the resultant of 2 vectors be zero

Yes, when the 2 vectors are same in magnitude and direction

Yes, when the 2 vectors are same in magnitude but opposite in sense

Yes, when the 2 vectors are same in magnitude making an angle of \(\frac{2\pi}{3}\) with each other

Text Solution

Verified by Experts

The correct answer is:

For two vectors \vec{A} and \vec{B} , the resultant is

\vec{R} = \vec{A} + \vec{B}

For the resultant to be zero,

\vec{A} + \vec{B} = 0

which implies

\vec{B} = - \vec{A}

Therefore, the two vectors must have:

• Equal magnitudes

• Opposite directions (opposite sense)
