Answer of the homework question: (C) option Solution: (i) force of gravity = mg S = 1km = 10³ m Wg = mgh = 10-³ × 10 × 1000 = 10J => answer of the first part (ii) when the Drop falls a force called gravity acts downwards and due to its acceleration a force ma acts in the upward direction along with the air drag. So Air drag = mg - ma ......................(i) But a is unknown The drop is freely falling and hence the initial velocity = 0 Final velocity = 50 m/s So v² = u² + 2aS => a = v²/2S. As u = 0. After Putting the values, we get a = 1.25 m/s² Substituting the values in eqⁿ (i), we get, Air drag = 8.75 × 10-³ Work done by it would be -ve as the S and F are at the angle of 180°. So, Wa = - Air drag × S = - 8.75 × 10-³ × 10³ = - 8.75 J And this is the answer of the 2nd part Sir please reply
