Its so confusing for me... in Ohm's law V=IR here V is independent variable and I is dependent variable (i,e increasing V, I also increases) here we place R (proportionality constant) with I (dependent variable). On the other hand.. in electrostatic force F=k(Qq/r^2 ) here K is constant...

Hello. A drop falling in air moves with terminal velocity (uniform velocity) when drag force balances its weight. But when charged droplet moves in electric field (In Millikan's Oil drop Method when there is vaccume between two plates) it is suspended between two plates when electric force...

Can anyone give answer? which scientist introduced the concept of variable velocity?

hi. I want to know that... who introduced the concept of variable velocity? Aladin

what is mean by "charge in an electrostatic equilibrium" ?? In my textbook the definition of the potential difference is that "The workdone on a unit positive charge carrying it from one point to the other kepping the charge in electrostatic equilibrium" In my textbook electrostatic mean...

it is not my home work I am just trying to solve it because I am learning basic math.so please help me in solving this equation

please help me in solving this question. 3x^2+xy-y^2=81 ; x+y=7 I will be thankful to you

What is high grade ceramic and carbon resistors are made from high grade ceramic why ? why they are made from carbon ? please explain reasons

Hello. Sir My question is that:Why magnetic field deflects a charge particle or a charged particle experiences a force in a magnetic field?Ok In electric field between two parallel plates a +ve charge particle deflects towards -ve plate when it is thrown perpandicularly. But in magnetic...

My question related snap in shown.please tell me why field lines are curved at the end of plates?

Hello. I can't understand that why electric field lines are radial between two parallal plates but curved at the end.? what is the reason.

Ok The example is that I am taking fro my textbook. Find an equation of the circle passing through the points A(1,2) and B(1,-2) and touching to the line x+2y+5=0

I can't understand the different conditions given and from that equation of the circle is found.For example. How equation of the circle can be found ? if two points on circle are given and equation of line tangent to the circle is given? thank you.

really really sorry Halsof actualy it is 1/(2-sqrt3). I will be thankful to you if you find the inverse of this.

Q.1: How can we find the inverse of a fraction? e.g . 1/2-(sqrt)3 . Q.2: A' intersection (A union U). what will be the answer?
