Question Nahi Banta

aipmt neet 2011 nlm & frict q 3 Impulse is a vector quantity and its relation with linear momentum as  per Impulse - Momentum theorem is required to solve this problem .further relation between  momentum and velocity needs to be applied . its always better to clarify directions in such type of  problem where vectors are involved. since only magnitude is asked in the final answer so we should  get rid of negative sign in the end.

Twisted qus Q 1  in this video u will see how a seen qus can be twisted and can cause trouble to us .Try to solve first by  urself and if still u want to see the solutions then u can find them in next upload only on my channel  Question Nahi Banta

AIPMT/NEET 2008 Newton law's of motion & friction. Three forces are given so first we have to check whether they have zero resultant along x- axis. Other interesting thing is angle of 2N with axis. Qus : Three forces acting on a body are shown in the figure. To have the resultant force only along the y  -direction, The magnitude of the minimum additional force needed is sol : पूरा solution देखकर अगर समझ आया तो क्या   आया । अगली बार फिर अटकोगे 🤨, अगर नहीं अटकना चाहते हो तो hint videos देखो और समझो 🧐 कि qus में किस चीज पर सबसे पहले ध्यान देना होता है ताकि अगली बार ऐसे सवाल खुद बनाओ   ️ और फिर solution ना देखना पड़े। अगर   concept नहीं आते तो concept के जो videos डालता हूं वो देखो और अगर फिर भी कोई help चाहिए तो मुझे contact करो। Interesting hint and related concept videos are also available on my channel Question Nahi Banta.

aipmt neet 2007 nlm frict q 1 sliding friction coefficient means kinetic friction and its a constant  force which opposes relative motion so in this qus we have to use of equation of motion along  with  concept of friction. for more info , watch this video 

aipmt neet 2006 nlm frict q 1 this is a qus based on the formula of average force which depends  on change in momentum and since momentum is a vector quantity so change in it or its  component needs to be taken care of . Rest u will understand after watching the video

Playlist includes not only the solution of qus but also the unique and interesting , hints ,concept and tips. After watching these ,ur concepts will definitely get better and u r going to solve qus in future with greater ease and confidence

 Q 1 )The position x of a particle with respect to time t along x-axis is given by x=9t2−t3 where x is in metres and t is in seconds. What will be the position of this particle when it achieves maximum speed along the + x direction? Description :  ghumao ghumao kind of question , position to velocity then application of knowledge of calculus ( maxima n minima) then again back to position. in short chances of making mistake while moving between different parameters. Q 2) A particle starting from the origin (0, 0) moves in a straight line in the (x,y) plane. Its coordinates         at a later time are (√3,3). The path of the particle makes with the x-axis an angle of Description : this question could( sabke liye ho aisa nahi hai) be a problem for those who don't know about how to calculate angle of position vector with axis so nahi aata toh nahi aata , koi baat nahi just ,watch n learn Q 3) A car moves from X to Y with a uniform speed vu and returns to ...

 Q 1 )A particle moves along a straight line OX. At a time t(in seconds) the distance x(in meters)of the particle from 0 is given by:-x=40+12t−t3.  How long would the particles travel before coming to rest? Sol 1 )  Q 2) The vectors A and B are such that | A + B| = |A - B| The angle between the two vectors is  Q 4) For angles of projection of a projectile at angles (45∘−θ) and (45∘+θ) , the horizontal ranges described by the projectile are in the ratio of: SOL 4)  Q 5) Two bodies, A(of mass 1kg) and B(of mass 3kg),are dropped from heights of 16 m and 25 m respectively. The ratio of the time taken by them to reach the ground is: Next time time want to do this type of qus by urself / want to learn most accurate way of problem solving/looking for similar qus based on this, then u must see other hint and related concept videos available on my channel Question Nahi Banta Feel free to contact Email : questionnahibanta@gmail.com ,You tube channel : Question Nahi Banta...
