Rivet is heated before fixing in hole to join two metal plates.

Consider the situation of the previous problem. Consider the fastest electron emitted parallel to the large metal plate. Find the displacement of this electron parallel to its initial velocity before it strikes the large metal plate.

3.5 kg mass of a metal plate has the volume of 1.5m^(3) . Find the density of metal plate.

The separation between the plates of a parallel-plate capacitor is 0.500 cm and its plate area is 100 cm^2. A 0.400cm thick metal plate is inserted into the gap with its faces parallel to the plates .Show that the capacitance of the assembly is independent of the position of the metal plate within the gap and find its value.

Two identical plates of different metals are joined to form a single plate whose thickness is double the thickness of each plate. lf the coefficients of conductivity of each plate are 2 and 3 respectively, then the conductivity of composite plate will be

An uncharged metal sphere is placed between two equal and oppositely charged metal plates. The nature of line of force will be

A small metal plate of work function phi is kept at a distance r from a singly ionised, fixed ion. A monochromatic light beam is incident on the metal plate and photoelectrons are emitted. Find maximum wavelength of the light beam so that some of that electrons may go round the ion along a circle.

If two normals to a parabola y^2 = 4ax intersect at right angles then the chord joining their feet pass through a fixed point whose co-ordinates are:
