MCQ
Two bodies $A$ and $B$ start from rest from the same point with a uniform acceleration of $2\,m / s ^2$. If $B$ starts one second later, then the two bodies are separated, at the end of the next second, by $.............\,m$
  • A
    $1$
  • B
    $2$
  • ✓
    $3$
  • D
    $4$

Answer

Correct option: C.
$3$
c
(c)

$s_B=\frac{1}{2} \times 2 \times(1)^2=1\,m$

$s_A=\frac{1}{2} \times 2 \times(2)^2=4\,m$

$s_A-s_B=3\,m$
