Deduce its relation with coefficient of limiting friction. Assertion :Angle of repose is equal to angle of limiting friction. Reason: When the body is just about to move, the force of friction in this stage is called as limiting friction. The coefficient of static friction between a block of mass m and an incline is μs = 0.3.
Deduce Ohm/s law using the concept of drift velocity. OR Define the term 'drift velocity' of charge carriers in a conductor.Obtain the expression for the current density in terms of relaxation time. OR Define relaxation time of the free electrons drifting in a conductor.How is it related to the drift velocity of free electrons?
(a) Draw the labelled ray diagram for the formation of image by a compound microscope. Derive an expression for its total magnification (or magnifying power), when the final image is formed at the near point.
An electric dipole is a separation of positive and negative charges. The electric dipole moment is the product of the magnitude of the charge and the distance between the centres of positive and negative charges. μ = Q×r. Here, Q is charge and r is the distance. Was this answer helpful?
According to drift velocity expression, the relaxation time is the time interval between successive collisions of an electron on increasing temperature, the electrons move faster and more collisions occur quickly. Hence, relaxation time decreases with increase in temperature which implies that drift velocity also decreases with temperature.

Define relaxation time of the free electrons drifting in a conductor: How is it related to the drift velocity of free electrons? Use this relation to deduce the expression for the electrical resistivity of the material.
Define centripetal acceleration. Derive an expression for the centripetal acceleration of a particle moving with uniform speed 'v' along a circular path of radius 'r'. Give the direction of this acceleration.
A block is moving on an inclined plane making an angle 45 0 with the horizontal and the coefficient of friction is μ. The force required to just push it up the inclined plane is 3 times the force required to just prevent it from sliding down.If we define N=10μ, then N is. Medium. View solution.
(a) Define a wavefront. Using Huygens' principle, verify the laws of reflection at a plane surface. (b) In a single slit diffraction experiment, the width of the slit is made double the original width. How does this affect the size and intensity of the central diffraction band ? Explain.
