Q. Two particles $A$ and $B$ start moving simultaneously from point $P$ with velocity 15 $ms^{- 1}$and 20$ms^{- 1}$ respectively. They move with equal accelerations but opposite in direction. When $A$ overtakes $B$ at $C$ then its velocity is 30$ms^{- 1}$. The velocity of $B$ at $C$ will lbe

A) 5$ms^{- 1}$
B) 10$ms^{- 1}$
C) 15$ms^{- 1}$
D) 20$ms^{- 1}$
Explanation

The correct answer is Option A: 5$ms^{- 1}$.
