Quick Test

(1 of 40) The ratio of relative strengths of the gravitational force and the electromagnetic force between two charged particles is

$10^{- 11}$
$10^{- 39}$
$10^{- 37}$
$10^{- 41}$

(2 of 40) The efficiency of an engine is given by

η = \frac{α β}{\sin θ} . \log_{e} \frac{β x}{κ T}

, where

α

and

β

are constants. If T is the absolute temperature,

κ

- Boltzmann constant,

θ

- angular displacement and x is distance, then the incorrect statement is

Dimensions of $β$ are same as that of force
Dimensions of $α^{- 1} x$ are same as that of energy
Dimensions of $η^{- 1} \sin θ$ are same as that of $α β$
Dimensions of $α$ are same as that of $β$

(3 of 40) A bird flies with a velocity (t-2)

{ms}^{- 1}

along a straight line, where t is the time in seconds. The distance covered by it in a time of 4 seconds is

(4 of 40) A car is travelling with linear velocity ‘V’ on a circular road of radius ‘r’. If its velocity is increasing at a rate of ‘a’

{ms}^{- 2}

, then the resultant acceleration will be

$\sqrt{(\frac{V^{2}}{r^{2}} - a^{2})}$
$\sqrt{(\frac{V^{4}}{r^{2}} + a^{2})}$
$\sqrt{(\frac{V^{4}}{r^{2}} - a^{2})}$
$\sqrt{(\frac{V^{2}}{r^{2}} + a^{2})}$

(5 of 40) Two blocks of masses

W_{1}

and

W_{2}

are suspended from the ends of a light string passing over a smooth fixed pulley. If the pulley is pulled up with an acceleration ‘g’, then the tension in the string will be

$\frac{4 W_{1} W_{2}}{W_{1} + W_{2}} g$
$\frac{2 W_{1} W_{2}}{W_{1} + W_{2}} g$
$\frac{W_{1} W_{2}}{W_{1} + W_{2}} g$
$\frac{W_{1} W_{2}}{2 (W_{1} + W_{2})} g$

(6 of 40) A body is moved along a straight line by an engine which delivers a constant power. The distance moved by the body in time ‘t’ is proportional to

$t^{\frac{1}{2}}$
$t^{\frac{3}{4}}$
$t^{\frac{3}{2}}$
$t^{2}$

(7 of 40) A body of mass 3 kg is moving under the action of a force which causes a displacement of

(\frac{t^{3}}{3}) m

, where ‘t’ is time in seconds. The work done by the force in first 2 seconds is

2 J
3.8 J
5.2 J
24 J

(8 of 40)

Two blocks of masses 2 kg and 1 kg are tied to the ends of a string which passes over a light frictionless pulley. The blocks are held at rest at the same horizontal level and then released suddenly. The distance traversed by their centre of mass in 2 seconds is

(Acceleration due to gravity =

10 {ms}^{- 2}

)

1.42 m
2.22 m
3.12 m
3.33 m

(9 of 40) A particle of mass ‘m’ is moving along a line y = x + a with a constant velocity ‘v’. The angular momentum of the particle about the origin is

mva
$mva \sqrt{2}$
$\frac{mva}{\sqrt{2}}$
$\frac{mva}{x \sqrt{2}}$

(10 of 40) A force of 6.4 N stretches a vertical spring by 0.1 m. If it were to oscillate with a period of

\frac{π}{4}

then the mass that is to be suspended from the spring is

$\frac{π}{4}$ kg
1 kg
$\frac{1}{π}$ kg
10 kg
