18) \( \mathrm{P}, \mathrm{Q}, \mathrm{R} \) are three collinear points. Given that \( \overrightarrow{P R}=14 u \) and Q divides \( P R \) internally in the ratio \( 3: 4 \). State the following vectors in terms of \( u \). \( P, Q, R \) ialah tiga titik segaris. Diberi bahawa \( \overrightarrow{P R}=14 u \) dan \( Q \) membahagi \( P R \) dalaman dengan nisbah \( 3: 4 \). Nyatakan vektor berikut dalam sebutan \( u \). (a) \( \overrightarrow{P Q} \) (b) \( \overrightarrow{R Q} \)
