MCQs Solution • Chapter 2: Vectors and Equilibrium • Physics Class 11 • Federal and KPK Board

#physics #federal_board #mcqs
this video consist and detailed solution of MCQs from chapter number 2 of Physics class 11.
Two vectors lie with their tails at the same point. When the angle between them is increased by 20° their scalar product has the same magnitude but changes from positive to negative. The original angle between them was:
(A) 0 (B) 60° (C) 70° (D)80°
The minimum number of vectors of unequal magnitudes required to produce zero resultant is
(A) 2 (B) 3 (C) 4 (D)5
If the resultant of two vectors, each of magnitude A is also a vector of magnitude A, the angle between the two vectors will be
(A) 30° (B) 45° (C) 60° (D)120°
The magnitude of vector A = 2î + ĵ + 2k̂ is
(A) 9 (B) 5 (C) 3 (D) 1
and so on

Great sir

[@AlphaSciAcademy]

Thanks 👍

[@m.saleem5520]

Very good sir
Your voice gives knowledge and solve the problems mostly the teacher talk loudly fastly and not providing physics thanks

[@AlphaSciAcademy]

Thank you so much 😊 stay happy 😊

[@azmatali5296]

excellent

[@AlphaSciAcademy]

Thanks 👍

Sir mcat men calculator allowed nai hota to ye cos inverse kese nikalte hen ?

[@AlphaSciAcademy]

Make a table of all these trigonometric functions and practice to remember these values. Thanks 👍

[@MalikBilal-wm2jb]

AOA
Ap videos kis trah bnaty hn ye likhty kesy hn koi tablet ha?

Question 6 has answer of 20 according to 2nd condition of equilibrium

[@AnasIsrar-pf1sj]

20 cm answer jo ata hai wo pivot point se dore hai. 50 se 20 k dori pr 30 ata hai.

[@user-xi5iv7qk3q]

Thanks sir, but mcqs no 3 long question hona chaye tha😢

[@AlphaSciAcademy]

Yeah 😅

[@shamsulqamarehsaas4641]

Yes of course
