Position of an ant (S in metres) moving in YZ plane is given by $S= 2t^2 \hat j + 5 \hat k$ (where t is in second)
Position of an ant (S in metres) moving in YZ plane is given by $S= 2t^2 \hat j + 5 \hat k$ (where t is in second). The magnitude and direction of velocity of the ant at t = 1 s will be : (A) 16 m/s in ydirection (B) 4 m/s in xdirection (C)…

DPP Worksheet for NEET
So at last I started working. Sometimes, we want to study a topic in physics and sometimes we need to revise a topic in physics, we need worksheet for this. Since you are preparing for NEET, which is a MCQ based test, you have to do as many questions as possible. If not for all…

So Let’s Start.
The purpose of starting PhysicsCookBook is to help my students with the understanding of physics. Due to some personal reasons, after some initial days, I left it untouched. Now things settled and I am planning to start it again. I am not the video kind of guy. I don’t like my learning from videos. On…

An electric dipole is formed by two charges +q and –q located in xyplane at (0, 2) mm
Question: An electric dipole is formed by two charges $+q$ and $–q$ located in $xyplane$ at $(0, 2)$ mm and $(0, –2)$ mm, respectively, as shown in the figure. The electric potential at point $P(100, 100)$ mm due to the dipole is $V_0$. The charges $+q$ and $–q$ are then moved to the points $(–1,…

Our First Post on Physics CookBook
Welcome to Physics CookBook. If you haven’t read the about page, I suggest you to read it. Since this is my first post, This is all about the introduction of Physics CookBook. I am Syed Mazhar Ali. I am teaching physics from 1996. If you are a student, you were not probably born. Barring a…
