A mass m is thrown vertically upward into air with initial speed u. A constant force F due to air resistance acts on the mass during its travel. Taking into account the work done against air drag the maximum distance covered by the mass to reach the top is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Loss is K.E. = Gain in P.E. + Work done against air drag
i.e. 
mu 2 = mgh + Fh = h (mg + F)
or h = 
=
