Let's Talk #3D Geometry!

 Hello Readers,





Useful formulae:

Equation of line passing through two points  and  can be given as





Image of a point  in plane  can be given as





Position of two points  and  w.r.t plane

if  then points lie on the same side of plane.

if  then points lie on opposite side of plane.

The follow up questions require you to just guess the correct approach. So, keep your pen aside and attack!

Measuring Instrument (Free Marks in Exams)🤑

work in progress! Wait for final Blog.   Did you know!😯 2 questions have been asked in JEE-Main and 3 in JEE-Advanced on this concept in last 10 years . The measurement of length is necessary in almost all the experiments in Physics. There are experiments where greater accuracy is not required. In such experiments, a meter scale is used to measure distances correctly up to a millimetre. To measure a length correctly up to a fraction of a millimetre, the division must be subdivided. Hence, a meter scale cannot be used in measurements that requires greater accuracy. For accurate measurement up to  or  of a millimetre, there are various devices that can be used, such as (A) Vernier caliper                              (B) Screw gauge (I) Vernier caliper:- A Vernier caliper consists of a rectangular steel bar such that inch is marked on one edge and centimetre is on the other edge, as shown in the fig...

Pacemaker! How does it works?

  The consistent beating of heart is the very basic process, which keeps all of us alive on this beautiful planet. Unfortunately, some people develop heart problems in their old age. This makes their heart beat slower and inconsistent. It happens due to problems in the sinoatrial node. Sinoatrial node is a part of heart, which sends electrical signals to heart. These electrical signals are vital to make the heart function properly. In order to make heartbeats consistent, pacemaker is used. Pacemaker is a device with the following components. 1. A battery 2. A microprocessor control switch 3. An RC circuit Let us understand how this pacemaker works. The battery charges the capacitor present in the RC circuit. Then, a computer-controlled switch disconnects the battery and connects the charged capacitor with the heart by a wire. This gives a pulse to the heart and it regains the desired beating frequency. After the capacitor is discharged, the computer-controlled switch disconnects t...
