Two flawlessly conducting spheres are in an evacuated region of space. One is at a potential of 12 volts as well as the other is at a potential of 15 volts. A free electron is released as of rest at the surface of the sphere at -12 volts. With what speed does it collide into the other sphere? (The mass of an electron is 9.11 × 10-31 kg.)
Bending moment : The diagram in created shear forces, but the applied forces also create bending. Consider a section x x' at a distance x measured from end B. Then R B
In Bohr's theory of the atom, what force was responsible for holding the electrons in their orbit? Ans: Coulomb force or the force of attraction among the proton (nucleus) a
The free surface of a liquid always has a tendency to contract and possess minimum surface area. If we want to enhance the surface area of the liquid, work has to be done. This wor
Q. Does sunlight reflected off a mirror raise the temperature of the sun-rays? Answer:- A standard planar mirror will not raise the energy contained in the rays that refle
The energy band formed by a series of energy levels having valence electrons is called as valence band. At 0 K, the electrons fulfill the energy levels in valence band initialising
