\mathrm{\vec A}\mathrm{.\vec B} = AB,

, then the angle between

\mathrm{\vec A}\,\mathrm{and}\,\mathrm{\vec B}

View answer and explanation

Correct option: A

{0^0}

\mathrm{\vec A}\mathrm{.\vec B} = AB

, then the angle between

\mathrm{\vec A}\,\mathrm{and}\,\mathrm{\vec B}

{0^0}

because

\cos \theta = 1

when

\theta = 0
