The mass of a proton is 1847 times that of an electron. A electron and a proton are injected into a uniform electric field at right angle to the direction of the filed with the same initial K.E.

A photo cell is illuminated by a small bright source placed 1 m away. When the same source of light is placed 2 m away, the electrons emitted by photo cathode

A stick of length L and mass M lies on a frictionless horizontal surface on which it is free to move in any way. A ball of mass m moving with speed V collides elastically with the stick as shown in fig below. If after the collision, the ball comes to rest, then what should be the mass of the ball?

To reduce the range of voltmeter, its resistance need to be reduced. A voltmeter has resistance \(R_o\) and range \(V\). Which of the following resistances when connected in parallel will convert it into a voltmeter of range \(\frac Vn\)?

A uniform rod of length l is free to rotate in a vertical plane about a fixed horizontal axis through B. The rod begins rotating from rest from its unstable equilibrium position. When, it has turned through an angle 8, its angular velocity ω is given by

A uniform electric field and a uniform magnetic field acting along the same direction in a certain region. If an electron is projected along the direction of the fields with a certain velocity, then

Two identical conducting balls \(A\) and \(B\) have positive charges \(q_1\) and \(q_2\) But \(q_1≠q_2\). The balls are brought together so that they touch each other and then kept in their original positions. The force between them is

A positively charged ball hangs from a silk thread. We put a positive test charges \(q_o\) at a point and measure \(\frac {F}{q_o}\), then it can be predicted that the electric field strength \(E\)

The following circuit represents:

Capacitor \(C_1\) of capacitance \(1\ μF\) and capacitor \(C_2\) of capacitance \(2\ μF\) are separately charged fully by a common battery. The two capacitors are then separately allowed to discharged through equal resistors at time \(t = 0\)

The maximum numbers of possible interference maxima for slit separation equal to twice the wavelength in Young's double slit experimentis

The half-life period of a radioactive element X is same as the mean life of another radioactive element Y. Initially, both of them have the same numbers of atoms then,

In the given figure, what is the magnetic field induction at point O.

An isotropic point source of light is suspended h metre vertically above the centre of circular table of radius r metre. Then, the ratio of illumenances at the centre to that at the edge of the table is

A source emits electromagnetic waves of wavelength 3 m. One beam reaches the observer directly and other after reflection from a water surface, travelling 1.5 m extra distance and with intensity reduced to \(\frac 14\) as compared to intensity due to the direct beam alone. The resultant intensity will be

A long block A of mass \(M\) is at rest on a smooth horizontal surface. A small block B of mass \(\frac M2\) is placed on A at one end and projected along A with some velocity \(v\). The coefficient of friction between the block is \(μ\). Then, the accelerations of blocks A and B before reaching a common velocity will be respectively.
