The instantaneous voltages at three terminals marked \(X,Y\) and \(Z\) are given by
\({V_x} = {V_0}\,\sin \,\omega t,\)
\({V_Y} = {V_0}\,\sin\) \(\left( {\omega t + {{2\pi } \over 3}} \right)\)
and $$Vz = {V_0}\sin \left( {\omega t + ...

In Process 1, the energy stored in the capacitor EC and heat dissipated across resistance ED are related by

In Process 2, total energy dissipated across the resistance ED is

A photoelectric material having work-function \({\phi _0}\) is illuminated with light of wavelength \(\lambda \left( {\lambda < {{he} \over {{\phi _0}}}} \right).\) The fastest photoelectron has a de-Broglic wavelength \({\lambda _d}.\) A ...

A source of constant voltage V is connected to a resistance R and two ideal inductors L1 and L2 through a switch S as shown. There is no mutual inductance between the two inductors. The switch S is initially open. At t = 0, the switch is cl...

A point charge \(+Q\) is placed just outside an imaginary hemispherical surface of radius \(R\) as shown in the figure. Which of the following statements is/are correct?

A rocket is launched normal to the surface of the Earth, away from the sun, along the line joining the Sun and the Earth. The Sun is \(3 \times 10{}^5\) times heavier than the earth and is at a distance \(2.5 \times {10^4}\) times larger t...

A symmetric star shaped conducting wire loop is carrying a steady state current \({\rm I}\) as shown in the figure. The distance between the diametrically opposite vertices of the star is \(4a.\) The magnitude of the magnetic field at the c...

A uniform magnetic field \(B\) exist in the region between \(x=0\) and \(x = {{3R} \over 2}\) (region \(2\) in the figure) pointing normally into the plane of the paper. A particle with charge \(+Q\) and momentum \(p\) directed along \(x\)-...

Consider an expanding sphere of instantaneous radius R whose total mass remains constant. The expansion is such that the instantaneous density \(\rho\) remains uniform throughout the volume. The rate of fractional change in density $$\left...

Three vectors \(\overrightarrow P ,\overrightarrow Q\) and \(\overrightarrow R\) are shown in the figure. Let \(S\) be any point on the vector \(\overrightarrow R .\) The distance between the points \(P\) and \(S\) is $$b\left| {\overrig...

A wheel of radius R and mass M is placed at the bottom of a fixed step of height R as shown in the figure. A constant force is continuously applied on the surface of the wheel so that it just climbs the step without slipping. Consider the t...

A rigid uniform bar AB of length L is slipping from its vertical position on a frictionless floor (as shown in the figure). At some instant of time, the angle made by the bar with the vertical is \(\theta\). Which of the following statement...

Consider regular polygons with number of sides \(n=3,4,5....\) as shown in the figure. The center of mass of all the polygons is at height \(h\) from the ground. They roll on a horizontal surface about the leading vertex without slipping an...

A person measures the depth of a well by measuring the time interval between dropping a stone and receiving the sound of impact with the bottom of the well. The error in his measurement of time is \(\delta T = 0.01\) seconds and he measures...

Two coherent monochromatic point sources \({S_1}\) and \({S_2}\) of wavelength \(\lambda = 600\,nm\) are placed symmetrically on either side of the center of the circle as shown. The sources are separated by a distance \(d=1.8\) \(mm.\) Th...
