Consider a drop of rain water having mass 1g falling from a height of 1km. It hits the ground with a speed of 50m/s. Take 'g' constant with a value 10m/s2.
The work done by the
(i) gravitational force and the
(ii) resistive force of air is :

Neet 2017 | W.P.E Q 1 | Two qus are asked in a single one but still qus is of average level. There are multiple forces involve so we will apply work energy theorem and work done by gravity i.e the conservative force. Practically it’s the non-conservative force i.e work done by resistance force that needs to be calculate.
