Two particles of medium disturbed by the wave propagation are at x1 = 0 and x2 = 1 cm. The respective displacements ( in cm) of the particles can be given by the equations: Two particles of medium disturbed by the wave propagation are at x1 = 0 and x2 = 1 cm. The respective [...]

At t = 0, the shape of a travelling pulse is given by y (x,0) = 4 * 10^-3 / 8 – (x)^2 where x and y are in metres. The wave function for the travelling pulse if the velocity of propagation 0) = 4 * 10^-3 / 8 - (x)^2 where x and y [...]

A plane sound wave is travelling in a medium. In reference to a frame A, its equation is y = a cos (omega t – kx). Which reference to frame B, moving with a constant velocity v in the A plane sound wave is travelling in a medium. In reference to a frame A its [...]

A charge 2μC is taken from inifinity point in an electric field, without changing its velocity. If work done against eletrostatic forces is −40μJ, then find the potential at that point. A charge 2μC is taken from inifinity point in an electric field then find the potential at that point. without changing its velocity. If [...]

The amplitude of a wave represented by displacement equation y = 1 /root a sin omega t + – 1 / root b cos omega t will be The amplitude of a wave represented by displacement equation y = 1 /root a sin omega t + - 1 / root b cos omega t will [...]

If you carry out the integral of the electric field ∫E→.d→l for a closed path like that as shown in (Fig. 3.40), the integral will always be equal tom zero, independent of the shape of the path and independent of where charges may be located relative to the path. Explain why. If you carry out [...]

Show that if at some part of a field the lines of force have the from of concentric circles whose centres are at point O (as given in Fig. 3.39), the field intensity at each point in this part of the field should be inversely proportional to the distance from the point O. Show that [...]

An infinity long uniform line charge distribution of charge per unit length λ lies parallel to the y-axis in the y−z plane at z = root 3 / 2 a (see figure). If the magnitude of the flux of the electric field through the rectangular surface ABCD lying in the x−y plane with its centre [...]
