In which of the following case no force
exerted by a magnetic field on a charge?

A long thin hollow metallic cylinder of radius
R has a current i ampere. The magnetic
induction B away from the axis at a distance r
from the axis varies as shown in

Which of the following type of wheels of
same mass and radius will have largest
moment of inertia?

A transistor is connected in common emitter configuration. The collector supply is \(8 \mathrm{~V}\) and the voltage drop across a resistor of \(800 \Omega\) in the collector circuit is \(0.5 \mathrm{~V}\). If the current gain factor $$\alp...

A spring is stretched by 0.40 m when a mass
of 0.6 kg is suspended from it. The period of
oscillations of the spring loaded by 255 g and
put to oscillations is close to (g = 10 ms\(^{-2}\))

A heavy brass sphere is hung from a spring
and it executes vertical vibrations with period
T. The sphere is now immersed in a
non-viscous liquid with a density (1/10 )th
that of brass. When set into vertical
vibrations with the sphere remai...

One of the rectangular components of a force
of 40 N is 20\(\sqrt3\) N. What is the other
rectangular component?

In a diffraction pattern due to a single slit of width \(a\), the first minimum is observed at an angle \(30 \Upsilon\) when light of wavelength \(500 \mathrm{~nm}\) is incident on the slit. The first secondary maximum is observed at an ang...

The sources of sound A and B produce a
wave of 350 Hz in same phase. A particle P is
vibrating under an influence of these two
waves. If the amplitudes at P produced by the
two waves is 0.3 mm and 0.4 mm, the
resultant amplitude of the poin...

A body of mass 8 kg, under the action of a
force, is displaced according to the equation, \(s=\frac{t^2}{4}\) m, where t is the time. Find the work done by the force in the first 4 s.
