  ● Pronouns  :-  Pronoun is a word which is used instead ( اس کي جگھ پر) of noun. Pronoun  is a word that refers to a noun. Pronoun is a word which takes place of a noun. Examples :- I ,we, you, he, she, it, they. • Ahmed is a good student. (Noun). • He is a good student.  (Pronoun). • Uzma eats mango. (Noun). • She eats mango.(Pronoun). Types of Pronouns • Personal Pronoun. • Possessive Pronoun. • Reflective Pronoun. • Demonstrative Pronoun. • Distributive Pronoun. • Indefinite Pronoun. • Intensive Pronoun. • Interrogative Pronoun. • Relative Pronoun. • Reciprocal Pronoun. ● Personal Pronoun:-           personal Pronouns are pronouns that that refers to a specific person or things in a sentence. It is divided into two groups nominative and objective. ● Nominative personal pronoun  act as a subject of a sentence (I, we, you,  he, she, it, they). Examples: I  go to school. We are brothers. ● Objective personal pronoun  It acts as a object of a sentence. (Me, us, you, him, h

            Have is used in two ways . ● One is used for possession or ownership. (Always used first form) ● Second is used for Present perfect tense.( 3rd form) Now in the possession there is always used first of of verb as a model verb. Here it is model verb and in the model verb never be used 2nd and 3rd form of verb. Examples. I have a car. Do I have a car. I do not have a car. He has a car 🚗 Does he have a car . ( Note : in the singulars has changed into have) But in the present perfect tense used 3rd form of verb and never be used 2nd form of verb. I have gone to karachi.  مان ڪراچي وڃي چڪو آهيان۔ Me Karachi ja chuka ho. I have eaten mangoes.

  Problem 3 Published On  By Problem 3:   Three point  charges  each of 4 micro C are placed at three corners of a square of side 20cm. Find the magnitude of force on each. Since r 1 , r 2  and r 3  form right-angeled triangle, so applying Pathagorous theorem to find the value of r 3 : r 3 2 =r 1 2 +r 2 2 r 3 2 =(20cm) 2 +(20cm) 2 r 3 2 =400cm 2 +400cm 2 r 3 2 =800cm 2 r 3 =28.28cm Given: q 1 =q 2 =q 3 = 4microC = 4 x 10 -6 C. Force on Q 1 : Force  on Q 1  due to Q 2  (F 12 ) F 12 =Kq 1 q 2 /r 1 2 F 12 =9x10 9 (4x10 -6 )(4x10 -6 )/(0.2) 2 F 12 =3.6N. Force on Q 1  due to Q 3  (F 13 ) F 13 =Kq 1 q 3 /r 3 2 F 13 =9x10 9 (4x10 -6 )(4x10 -6 )/(0.2828) 2 F 13 =1.8N. Resultant  Force: According to vector  addition , if two vectors having  magnitudes  a and b are making angle X, then  magnitude  of resultant vector r can be found by the  formula : r 2 =a 2 +b 2 +abcosX. So similarly, F 2 =F 12 2 +F 13 2 +2F 12 F 13 cos45 o . F 2 =(3.6) 2 +(1.8) 2 +2(3.6)(1.8)(0.707) F 2 =25.364 F=5.04N. (Ans)

  Find the area of rectangular plate having length (21.3 ± 0.2 ) cm and width (9.8 ± 0.1 ).  Area = ?  Length = (21.3 ± 0.2 )  Width = (9.8 ± 0.1) Here Area = Length × Width  Area = (21.3 ± 0.2 ) × (9.8 ± 0.1)  Area = 21.3 ( 9.8 ± 0.1) ± 0.2 (9.8 ± 0.1)  Area = 208.74 ± 2.13 ± 1.96 + 0.02  Area = 208.74 + 0.02 ± 2.13 ± 1.96 ▭ (Area = 208.76 ±4.09)

  Calculate the circumferences of a circle of radius 3.5 cm and area of a circle of radius 4.65 cm.  Circumference of circle = S = ?  Radius = 3.5 cm  Area = ? Radius = 4.65 cm  Solution (a):  S = 2πr  S = 2 × 3.14 ×3.5  (S=21.98 cm)  Now find the area of circle A = πr^2 A = 3.14 × 〖4.65〗^2  A = 3.14 × 21.6225 (A=67.89 〖cm〗^2 ).

   • Al-Beruni was born in a small town Berun in present in Uzbekistan in 5 September 973 A.D and died in 13 December 1048 A.D Ghazni Afghanistan.   • He is father of comparative religion and modern geodesy (earth science,  accurate  measurement and understanding). • In 1017 He travelled to India 🇮🇳,  he studied the language,  religion and philosophy of Hindus 🕉 and wrote a book in them " Tarrekh ul Hind", so  He is called founder of  Indology.  • He Rejected (refuted) many theories and define them from new direc-tion.  • He rejected the theory that earth is flat and practically proved that earth is round. • He determined the densities of different substances. • He  wrote  more than one  hundred and fifty books  on various subjects such as mathematics, physics, cosmology, geography, history culture and civilization, archaeology, comparative religious, geology chemistry and biology and many others. • He gave the method of determining the longitude and latitude of a place.
