Which answer would be correct

Dear Student,

Acceleration due to gravity, g = 9.8 ms^-2

Net acceleration of the body downward is, a = 9.5 ms^-2

Let, F be the force due to air drag,
                                 F_air = ma_air

Since the body has the net acceleration ‘a’ in the downward direction,

Therefore,

ma = mg - ma_air

=> F_air = mg – ma

=> F_air = 0.05 (9.8 – 9.5) = 0.015 N

Hence, option 1 is correct.
