Quick Test

(1 of 200) Two charged spherical conductors of radius

R_{1}

and

R_{2}

are connected by a wire. Then the ratio of surface charge densities of the spheres

(σ_{1} / σ_{2})

is:

$\frac{R_{1}}{R_{2}}$
$\frac{R_{2}}{R_{1}}$
$\sqrt{(\frac{R_{1}}{R_{2}})}$
$\frac{R_{1}^{2}}{R_{2}^{2}}$

(2 of 200) The velocity of a small ball of mass M and density d, when dropped in a container filled with glycerine becomes constant after some time. If the density of glycerine is

\frac{d}{2}

, then the viscous force acting on the ball will be:

$\frac{Mg}{2}$
Mg
$\frac{3}{2} Mg$
2Mg

An infinitely long straight conductor carries a current of 5 A as shown. An electron is moving with a speed of $10^{5}$ m/s parallel to the conductor. The perpendicular distance between the electron and the conductor is 20cm at an instant. Calculate the magnitude of the force experienced by the electron at that instant.

$4 \times 10^{- 20} N$
$8 π \times 10^{- 20} N$
$4 π \times 10^{- 20} N$
$8 \times 10^{- 20} N$

A dipole is placed in an electric field as shown. In which direction will it move?

towards the left as its potential energy will increase.
towards the right as its potential energy will decrease.
towards the left as its potential energy will decrease.
towards the right as its potential energy will increase.

(5 of 200) A lens of large focal length and large aperture is best suited as an objective of an astronomical telescope since:

a large aperture contributes to the quality and visibility of the images.
a large area of the objective ensures better light gathering power.
a large aperture provides a better resolution.
all of the above.

(6 of 200) A screw gauge gives the following readings when used to measure the diameter of a wire
Main scale reading: 0 mm
Circular scale reading: 52 divisions
Given that 1mm on main scale corresponds to 100 divisions on the circular scale. The diameter of the wire from the above data is:

0.52 cm
0.026 cm
0.26 cm
0.052 cm

(7 of 200) A nucleus with mass number 240 breaks into two fragments each of mass number 120, the binding energy per nucleon of unfragmented nuclei is 7.6 Me V while that of fragments is 8.5 MeV. The total gain in the Binding Energy in the process is:

0.9 MeV
9.4 MeV
804 MeV
216 MeV

(8 of 200) A small block slides down on a smooth inclined plane, starting from rest at time t=0. Let

S_{n}

be the distance travelled by the block in the interval t=n-1 to t=n. Then, the ratio

\frac{S_{n}}{S_{n + 1}}

is:

$\frac{2 n - 1}{2 n}$
$\frac{2 n - 1}{2 n + 1}$
$\frac{2 n + 1}{2 n - 1}$
$\frac{2 n}{2 n - 1}$

$60 °$
$30 °$
$45 °$
$90 °$

(10 of 200) A spring is stretched by 5cm by a force 10N. The time period of the oscillations when a mass of 2kg is suspended by it is:

0.0628 s
6.28 s
3.14 s
0.628 s
