A particle has a velocity \( u \) towards east at \( t=0 \). Its acceleration is towards west and is constant. Let \( x_{A} \) and \( x_{B} \) be
\( \mathrm{P} \) the magnitude of displacement in the first 10 seconds and the

W next 10 seconds :
(A) \( x_{A}x_{B} \)
(B) \( x_{A}=x_{B} \)
(C) \( x_{A}x_{B} \)
(D) The information is insufficient to decide the relation of \( x_{A} \) with \( x_{B} \)
