A spherical steel ball released at the top of along column of glycerin of length `l` falls through a distance `l//2` with accelerated motion and the remaining distance `l//2` with uniform velocity let `t_(1)` and `t_(2)` denote the times taken to cover the first and second half and `w_(1)` and `w_(2)` are the work done against gravity in the two halves, then compare times and work done.

A

`t_(1) lt t_(2), W_(1) gt W_(2)`

B

`t_(1) gt t_(2), W_(1) lt W_(2)`

C

`t_(1) = t_(2), W_(1) = W_(2)`

D

`t_(1) gt t_(2), W_(1) = W_(2)`
