If the energy, $E = G^p \,h^q \,c^r$, where $G$ is the universal gravitational constant, $h$ is the Planck?? constant and $c$ is the velocity of light, then the values of $p$, $q$ and $r$ are, respectively
Four holes of radius $R$ are cut from a thin square plate of side $4R$ and mass $M$. The moment of inertia of the remaining portion about z-axis is
X-ray astronomy is possible only from satellites orbiting the earth. Efficiency of X-rays telescope is large as compared to any other telescope.
Two balls of different masses are thrown vertically upward with same speed. They will pass through their point of projection in the downward direction with the same speed. The maximum height and downward velocity attained at the point of projection are independent of the mass of the ball.
In javelin throw, the athlete throws the projectile at an angle slightly more than 45$^{\circ}$. The maximum range does not depend upon angle of projection.
The apparent weight of a body in an elevator moving with some downward acceleration is less than the actual weight of a body. The part of the weight is spent in producing downward acceleration, when body is in elevator.
The fundamental frequency of an open organ pipe increases as the temperature is increased. As the temperature increases, the velocity of sound increases more rapidly than length of the pipe.
The change in kinetic energy of a particle is equal to the work done on it by the net force. Change in kinetic energy of particle is equal to the work done only in case of a system of one particle.
An AC ammeter is used to measure current in a circuit. When a given direct current passes through the circuit, the AC ammeter reads 3 A. When another alternating current passes through the circuit, the AC ammeter reads 4 A. Then the reading of this ammeter, if DC and AC flow through the circuit simultaneously, is
A reversible engine converts one-sixth of the heat input into work. When the temperature of the sink is reduced by 62$^{\circ}$C, the efficiency of the engine is doubled. The temperatures of the source and sink are
A liquid is kept in a cylindrical vessel which is being rotated about a vertical axis through the centre of the circular base. If the radius of the vessel is $r$ and angular velocity of rotation is $\omega$, then the difference in the heights of the liquid at the centre of the vessel and the edge is
A capillary tube of radius $r$ is immersed in water and water rises in it to a height $h$. The mass of water in the capillary tube is $5\,g$. Another capillary tube of radius $2\,r$ is immersed in water. The mass of water that will rise in this tube is
A block of mass $10\, kg$ is moving in $x$-direction with a constant speed of $10\, m / s$. It is subjected to a retarding force $F=-0.1 \times J / m$ during its travel from $x=20\, m$ to $x=30\, m$. Its final kinetic energy will be :
A $12\, HP$ motor has to be operated $8\, h /$ day. How much will it cost at the rate of $50$ paise/kWh in 10 days?
A body of mass $m$ rises to a height $h=\frac{R}{5}$ from the earth's surface where $R$ is earth's radius. If $g$ is acceleration due to gravity at the earth's surface, the increase in potential energy will be
When an ideal monoatomic gas is heated at consant pressure, fraction of heat energy supplied which increases the internal energy of gas, is
The ratio of the dimensions of Plancks constant and that of the moment of inertia is the dimensions of
A network of four capacitors of capacities equal to $C_{1}=C, C_{2}=2 C, C_{3}=3 C$ and $C_{4}=4 C$ are connected to a battery as shown in the figure.
The ratio of the charges on $C_{2}$ and $C_{4}$ is
Application of a forward bias to a $p-n$ junction
A force $F$ is applied on the wire of radius $r$ and length $L$ and change in the length of wire is $l$. If the same force $F$ is applied on the wire of the same material and radius $2\, r$ and length $2\, L$, then the change in length of the other wire is
The work functions for metals $A, B$ and $C$ are respectively $1.92\, eV,\, 2.0\, eV$ and $5\, eV$. According to Einstein's equation, the metal(s) which will emit photoelectrons for a radiation of wavelength $4100\,?$ is/are
A $1\, kg$ stone at the end of $1\, m$ long string is whirled in a vertical circle at constant speed of $4\, m / s$. The tension in the string is $6\, N$, when the stone at $\left(g=10\, m / s ^{2}\right)$
