Question 2

The reason of current flow in p-n junction in forward bias is

Question 3

If V = ar where a is a constant and r is the distance, then electric field at a point will be proportional to

Question 4

Charges +q and –q are placed at points A and B, respectively; which are at a distance 2L apart, C is the midpoint between A and B. The work done in moving a charge +q along the semicircle CRD is :

Question 5

Pressure of an ideal gas is increased by keeping temperature constant. What is effect on kinetic energy of molecules?

Question 6

In Carnot engine efficiency is 40% at hot reservoir temperature T. For efficiency 50%, what will be temperature of hot reservoir?

Question 7

What will be the gravitational potential at center of the square plate of mass ‘4m’ having side ‘L’, when four glasses, each of mass ‘2m’ are placed at four vertices of the square plate?

Question 8

What will be the ratio G₁/ G₂, where G₁ is the gravitational potential energy of a system consisting of two equal point masses separated by a fixed distance When the masses of the particle are doubled, and their separation increases 4 times, the new gravitational potential energy is G₂.

Question 9

The potential difference applied to an X-ray tube is increased. As a result, in the emitted radiation
