The time interval will be Option B (0.02 s).
The given values in the question are:
Distance,
D = 0.2 m
Speed,
S = 0.1 m/s
As we know the formula,
→ [tex]Speed = \frac{Distance}{Time}[/tex]
or,
→ [tex]Time = \frac{Distance}{Speed}[/tex]
By substituting the values, we get
→ [tex]= \frac{0.2}{0.1}[/tex]
→ [tex]= 0.02 \ s[/tex]
Thus the above answer is right.
