Physics 2nd Half Syllabus Test

A parallel plate condenser has uniform electric field E(V/m) in the space between the plates. if the distance between the plates is d(m) and area of each plate is A(m²) the energy (joules) stored in the condenser is.

When hydrogen atom is in its first excited level its radius is.

In the nth orbit, the energy of an electron $$E_n=\frac{13.6}{n^2}eV$$  for hydrogen atom. The energy required to take the electron from first orbit to second orbit will be

Energy of electron in a orbit of H-atom is

X-rays of λ=1A° have frequency

How is the potential within and on the surface of a conductor?

The diagram shows the electric field lines in a region of space containing two small

charged spheres (Y and Z). Then

A cell of emf 5V and internal resistance 1 Ω will give maximum power output to

A charged particle enters a magnetic field such that the direction of initial velocity is different from the direction of the field. Which of the following characteristics of the particle will not change with time?

Figures show some equipotential lines distributed in space. A charged object is moved from point A to point B.
