Three vectors P→,Q→\overrightarrow P ,\overrightarrow QP,Q​ and R→\overrightarrow RR are shown in the figure. Let SSS be any point on the vector R→.\overrightarrow R .R. The distance between the points PPP and SSS is b∣R→∣.b\left| {\overrightarrow R } \right|.b​R​. The general relation among vectors P→,Q→\overrightarrow P ,\overrightarrow QP,Q​ and S→\overrightarrow SS is : JEE Advanced 2017 Paper 2 Offline Physics - Motion Question 7 English
