Two parallel conductors carry current in opposite directions as shown in the figure. One conductor carries a current of \(20 \mathrm{~A}\). Point \(C\) is a distance \(d / 2\) to the right of a 20 A current. If \(d=18 \mathrm{~cm}\) and $$i...

The focal length of thin convex lens for red and blue rays are \(100 \mathrm{~cm}\) and \(98.01 \mathrm{~cm}\), respectively. There, the dispersive power of the material of the lens is

A solid sphere having mass \(m\) and radius \(R\) moves down a plane inclined at an angle '\(\theta\)'. Find the ratio between its acceleration when it rolls without slipping and its acceleration when it slides down the same plane without a...

A particle of mass $m$ is projected with a velocity \(v\) making an angle of \(45^{\circ}\) with the horizontal. The magnitude of angular momentum of the projectile about the point of projection when the particle is at its maximum height $$...

A uniform cube of side $a$ and mass $m$ rests on a rough horizontal table. A horizontal force $F$ is applied normal to one of the faces at a point that is directly above the centre of the faces at a point that is directly above the centre ...

In a \(n\)-\(p\)-\(n\) transistor \(10^{10}\) electrons enter the emitter in \(10^{-6}\) s. \(6 \%\) of the other electrons are lost in the base. The current transfer ratio will be.

Assuming the diodes to be of silicon with forward resistance zero, the current \(i\) in the following circuit is

In the formula \(X=3 Y Z^2, X\) and \(Z\) have dimensions of capacitance and magnetic induction respectively. The dimensions of \(Y\) is MKS system are.

The frequency of a sonometer wire is \(100 \mathrm{~Hz}\) When the weights producing the tensions are completely immersed in water, the frequence becomes \(60 \mathrm{~Hz}\) and on immersing the weights in a certain liquid, the frequency be...

A ball is allowed to fall from a height of \(10 \mathrm{~m}\). If there is \(30 \%\) loss of energy due to impact, then after one impact ball will go up to.
