Two forces $\vec{F_1}=5\hat{i}+10\hat{j}-20\hat{k}$ and →F2=10^i�

1.	Two forces $\vec{F_1}=5\hat{i}+10\hat{j}-20\hat{k}$ and →F2=10^i−5^j−20^k act on a single point. The angle between →F1 and →F2 is nearly
Answer» Two forces $\vec{F_1}=5\hat{i}+10\hat{j}-20\hat{k}$ and $_{2} = 10^i - 5^j - 20^k$ act on a single point. The angle between $_{1}$ and $_{2}$ is nearly
