Consider a drop of rain water having mass 1 g falling from a height of `1 km`. It hits the ground with a speed of `50 m//s` Take `g` constant with a volume `10 m//s^(2)`. The work done by the
(i) gravitational force and the
(ii) resistive force of air is :
A. (i)-10J, (ii) -8.25 J
B. (i)1.25 J, (ii) -8.25 J
C. (i)100 J, (ii) -8.25 J
D. (i)10J, (ii) -8.25 J
