Question
The distance x (in µm) covered by a molecule starting from point A at time t = 0 and stopping at another point B in given by the equation The distance between A and B ( in μm) is closed to
10.7
20.7
40.7
50.7
Solution
A.
10.7
Given that distance
On differentiating
For x to be maximum,
⇒ 4t - t2 = 0
⇒ t = 4
∴ Maximum distance
xmax =
=
= 16
xmax = 10.7
