    \draw (0,0) circle (1.3cm);

    % Tâm O
    \fill (0,0) circle (1.5pt) node[above left, xshift=-2pt] {$O$};

    % --- 2. Định nghĩa các tọa độ lực ---
    \coordinate (O) at (0,0);
    
    % SỬA LẠI Ở ĐÂY:
    % 1. Dùng ngoặc nhọn { } để tính toán được hàm sqrt
    % 2. F2 cần dấu TRỪ (-) để hướng sang trái
    \coordinate (F1) at ({2*sqrt(2)}, 0);   % Lực sang phải
    \coordinate (F2) at ({-4*sqrt(2)}, 0);  % Lực sang trái (số âm)
    
    \coordinate (F3) at (45:2);      % Lực chéo lên
    \coordinate (F4) at (-45:2);     % Lực chéo xuống

    % --- 3. Vẽ các vector lực ---
    
    % F2 (Sang trái)
    \draw[->] (O) -- (F2) node[above, near end] {$\vec{F}_2$};
    
    % F1 (Sang phải)
    \draw[->] (O) -- (F1) node[above, near end] {$\vec{F}_1$};
    
    % F3 (Nét đứt, chéo lên)
    \draw[->, dashed] (O) -- (F3) node[above right] {$\vec{F}_3$};
    
    % F4 (Nét đứt, chéo xuống)
    \draw[->, dashed] (O) -- (F4) node[below right] {$\vec{F}_4$};

    % --- 4. Vẽ ký hiệu góc ---
    % Tôi bỏ comment vẽ cung tròn để hình đẹp hơn
