If two vectors \overrightarrow{A} and \overrightarrow{B} having equal magnitude {\R} are inclined at an angle \theta, then [31-Jan-2024 Shift 2]

Correct Answer is : |→A+→B|=2Rcos(θ2)

|{ {\A}}^{\to}-{ {\B}}^{\to}|=\sqrt{2} {\R} \sin (\frac{\theta}{2})

|{ {\A}}^{\to}+{ {\B}}^{\to}|=2 {\R} \sin (\frac{\theta}{2})

|{ {\A}}^{\to}+{ {\B}}^{\to}|=2 {\R} \cos (\frac{\theta}{2})

|{ {\A}}^{\to}-{ {\B}}^{\to}|=2 {\R} \cos (\frac{\theta}{2})
