Q. Define: binding energy.
The energy equal of mass defect is called as binding energy.
∴ Binding energy = [ZmP + Nmn - m] c2
= Δm c2 . Here, Δm is the mass defect.
What is a zone plate? How is it constructed? Show that a zone plate behaves like a convex lens. Deduce the expression for its focal length
Q Define: Drift velocity. Drift velocity is described as the velocity with which free electrons get drifted towards the positive terminal, when an electric field is applied.
Regard as an electron and a proton at an instant in time to be at a separation of 5 cm from each other. Presume the pair to be totally isolated from its surroundings in the vacuum
Core type Transformers: in this type of transformer the windings enclose the core (fig .given below). Both the windings are separated and half of every winding is placed on ever
Resistors in dc circuits: Components are said to be in series when they are connected end-to-end providing only one path for the current. Thus the same current passes through
Q. A coil of area of cross section 0.5 m 2 among 10 turns is in a plane perpendicular to a magnetic field of 0.2 wb / m 2 . Compute the flux through the coil.
Schwarzschild radius The radius r of the event horizon for Schwarzschild black hole of mass m is provided through (in geometrized units) r = 2 m. In conventional units, r =
A block of mass m is tied to a cord of length L that is pivoted at the center of a frictionless table. A second block of mass m is tied to the ?rst block also on a cord of length L
