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
@Purbi Siotia because work done by gravity is MgH=1×10^-3×10×1000=10J &Work done by all forces =change in Kinetic energy Wg+Wair=1/2mv^2-0as given (u=0) 10J+Wair=1/2×10^-3×50×50 10+Wair=1.25 So Wair=1.25-10=-8.75J Ans. Complete 👍🙂

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 Q:16 ka answer
576 mJ ho sakta hai kiya?
a= (d²x/dt²)= -8+6t
t=4s , a= 16
t=4s, S= (3×4)-(4×4²)+(4)³=12
W= FS = M.a.s = (3/1000) ×16×12= 576 m J
Please explain sir🙏🙏
NO . FORCE is Variable
Sote ni ho kya aap....
@@PhysicsWallah sir aap bachcho se bol dijiye ki comment section me spam aur tareef na kre....kisi ko doubt bhi hota h to vo top comments me nhi ayega..... Tareef gratitude ke form me honi chaiye ki dil se aankh band krke kisi insaan ko thank u bole....
Aur koi aapka constructive criticism krta h to ye log aise behave krte h jaise modi ki k andh bhakt.....

Idhar x ek variable he isko agar do baar differentiate karoge toh acceleration aega and wo variable hoga and hence force variable hoga

Solution bta do😊
@@checksnotes3014 for gravitation force apply mgh( keep m in kg and height in meter) ans will be positive since force and displacement are in same direction.
For air resistance
Word done by grav. + Word done by air = ∆ k.e

Ans -ve since air res. And displacement opposite ha

I was preparing for neet in 2016. I wish he was there and internet was cheap that time. I would have been doctor by now.
Ab nahi kr sakte?
Excuses are made by everyone. Students gave neet at that Time too and must have cracked it. We should stop hallucinating these things....
One who wanted to become a doctor at that time must had prepared well instead of making excuses.

Homework question
Ans1. Work done by gravitation force = Mgh on solving = 10J
Ans 2. Wg + Wr = 1/2mv²-0 = --8.75J
Therefore, OPTION C is correct
Option c
Exactly sis
Please explain ans 2
H.W. Ques 1 ans (i) 10j ans (ii) -8.75
Ques 2 ans mgl (1-cos theta)

Resistive force of air kaise calculate kiya???
@@safiyamufees8599 work energy theorm se kr skte hian...
