JEE Main 2024 (31 Jan, Shift 2) Physics Q32: If two…

Question

If two vectors $\vec{A}$ and $\vec{B}$ having equal magnitude $R$ are inclined at an angle $	heta$, then

Accepted Answer

Option 3: $|\vec{A}+\vec{B}|=2R\cos\left(\frac{	heta}{2}ight)$

Answer

$|\vec{A}+\vec{B}|=2R\sin\left(\frac{	heta}{2}ight)$

Answer

$|\vec{A}-\vec{B}|=2R\cos\left(\frac{	heta}{2}ight)$

Answer

$|\vec{A}+\vec{B}|=2R\cos\left(\frac{	heta}{2}ight)$

Answer

$|\vec{A}-\vec{B}|=\sqrt{2}R\sin\left(\frac{	heta}{2}ight)$
