Answer Key (Assignment: Chapter 14 Numerical Problems)

If you find any answer is provided wrong then let me know… And haan exponents ki mistake ho to usko khud dekh liye ga… Wo solve karty hue by mistake hojati hai

## Model Paper MCQs Solution

1. $A_y=Acos\theta$
2. cannot be replaced by a single equivalent force
3. less force is needed by the user
4. remain in the spacecraft
5. the height and the time of fall
6. the total K.E after impact is  $mv^2$
7. The total energy of the ball is constant throughtout the motion

## Material for Preparation for Exams

Go through this material … Solve everything… If there is something difficult or confusing, clear it before mid-term examinations.

CHAPTER 1 – MCQs w/ Solution

CHAPTER 2,3,4 – MCQs w/ Solution

CHAPTER 2,3,4 – THEORETICAL QUESTIONS & NUMERICAL PROBLEMS
For dimensional part of Chapter 1 – Go through five year papers – I’ll also discuss that in the class

Other than that there will be revision of Chapter 2 + difficult concepts of 3 & 4 and a discussion about “The Exam Paper Pattern of BIEK-XI Physics & How to solve that Question Paper”
