Variable Resistive FORCE || IIT JEE Mains – 2017 In HINDI - Videos

In this Physics video in Hindi for class 11 we gave solution of a numerical problem on work done by time varying force from IIT JEE Mains 2017 previous years’ question.
The question follows

A body of mass m = 10^-2 kg is moving in a medium and experiences a frictional force F = – kv^2. Its initial speed is v0 = 10 m/s. If after 10 s, its kinetic energy is 1/8 mv0^, The value of k will be –
